Written by Kinnari Ashar4th May 2023

If you're wondering what to apply before using a hair straightener, you're not alone. Frequent use of a straightener can cause damage, split ends, and dryness to your hair. However, using serum can help prevent these issues and leave you with healthy, shiny hair. In this article, we'll take a closer look at why serum can be so beneficial and why you should consider incorporating it into your hair care routine. So, let's dive in and learn about what to use before hair straightener.

Should I Use Serum Before Straightening My Hair: The Basics

If you're wondering what products to use before straightening hair, then a hair serum is the answer. It's a crucial step that can make all the difference in keeping your hair healthy and shiny. A hair serum acts as a protective shield for your hair against the high heat of the straightener. Not only that, but it can also help to prevent frizz and split ends. Using a good hair serum before straightening can leave your hair nourished, moisturized, and looking its best. Let us take a closer look at the reasons why you should use a serum before using a hair straightener.

6 Reasons Why You Should Use Serum Before Hair Straightening

1. Protects your hair from heat damage

Using a hair straightener can cause significant heat damage to your hair. When you apply heat to your hair, the high temperature can cause the hair shaft to break down, leading to split ends and breakage. By using a hair serum before straightening, you can create a protective barrier that shields your hair from the heat. This can significantly reduce the damage caused by the straightener.

If you are wondering what serum to use before straightening hair, here is your go-to product. You now get salon-style hair with the TRESemmé Gloss Ultimate Hair Serum. Infused with Vitamin E and a blend of nourishing coconut, conditioning macadamia, and moisturizing sunflower seed oils, this serum provides deep nourishment and a glossy shine to your hair. It protects hair from heat damage up to 230°C, making it more manageable and adding smoothness. Before styling, apply the serum to detangle, nourish, and boost shine, leaving you with a long-lasting floral fragrance that lasts up to 48 hours.

2. Adds shine to your hair

Hair serums are formulated with ingredients like silicones and oils that can add shine to your hair. These ingredients coat the hair shaft, smoothing the cuticle and reflecting light, making your hair appear shiny and healthy.

3. Tames frizz and flyaways

Serums can help to tame frizz and flyaways by smoothing down the hair cuticle. This can help to prevent moisture from penetrating the hair shaft and causing frizz. By using a serum before straightening your hair, you can achieve a sleek, smooth finish without any frizz or flyaways.

Transform your frizzy and unmanageable hair into smooth, shiny locks with TRESemmé Keratin Smooth Serum. Infused with the nourishing power of Argan oil, this serum will control frizz, add vibrancy and shine, and make your hair up to 2x stronger. Simply pump and apply it to damp hair from mid-length to ends after washing, and enjoy silky, smooth locks all day long.

4. Makes your hair more manageable

When you use a serum before straightening can make your hair more manageable by detangling and smoothing the hair. This can make it easier to comb through your hair and achieve a smooth, sleek finish.

5. Nourishes and repairs your hair

Hair serums often contain nourishing ingredients that can help to repair and strengthen your hair. For example, keratin is a protein that can help to strengthen the hair and prevent breakage. By using a serum with these ingredients, you can nourish and repair your hair, leaving it healthy and strong.

6. Increases the longevity of your hairstyle

Using a hair serum before straightening can also enhance the longevity of your hairstyle. By creating a protective barrier that seals in the style, you can prevent your hair from losing its shape or falling flat throughout the day. This can help you maintain a sleek, polished look all day long.

You may be wondering whether using a hair serum before hair straightening is worth the extra step in your hair care routine. The answer is a resounding yes! By using a serum before straightening your hair, you can protect your hair from heat damage and leave it looking healthy and shiny. Not only that, but hair serums also tame frizz and make your hair more manageable. With regular use, a hair serum can deeply nourish and repair your hair, leaving it strong and healthy. So, next time you reach for your hair straightener, make sure to apply hair serum before use, and you'll see the difference in no time!

We may also combine it with other information to improve our products, services, content, and advertising.

Ways in which we collect your personal data

We may collect personal data from a variety of sources. This includes:

Personal data you give us directly. We collect data about how you use our services and products, such as the types of content you view or engage with, or the frequency and duration of your activities. We also collect personal data you provide us when you sign up for a marketing newsletter, complete a survey or register for an account to buy our products. In so doing, we may ask for personal data, such as your name, gender, date of birth, address, email address, telephone number or credit card details. Some Unilever brands may collect “special categories of personal data” about you with your explicit consent. For more information on the special categories of data we collect and how we use it, please refer to the relevant section below.
Personal data we collect automatically. We also receive and store certain types of personal data whenever you interact with us online. For example, we use cookies and tracking technologies (to find out more, see our privacy key terms) to obtain personal data when your web browser accesses our websites or advertisements and other content served by or on behalf of Unilever on other websites. Your personal data is also collected when you search, buy, post, participate in a contest or questionnaire or communicate with our customer service teams. Examples of the types of personal data we collect include; IP address (to find out more see our privacy key terms), device ID, location data, computer and connection information such as browser type and version, time zone setting, browser plug-in types and versions, operating system, and purchase history – which Unilever sometimes aggregates with similar information from other consumers. During some of your internet browsing on Unilever’s websites we may also use software tools to measure and collect session information, including page response times, download errors, length of visits to certain pages, page interaction information, and methods used to browse away from the page. We may also collect technical information to help us identify your device for fraud prevention and diagnostic purposes.
Personal data we collect from other sources. We collect personal data from other sources including our trusted partnerships with third-parties and where we operate Unilever accounts on third-party platforms: For example, when you use the “like” functionality on Facebook or the +1 functionality on Google+. Additionally, we receive information about you and other visitors’ interactions with our advertising to measure whether our advertising is relevant and successful. We also collect information about you and your activities from a third-party when we jointly offer services or products, or from third-party data enrichment providers (to find out more see our privacy key terms) who may deliver insights to Unilever about the personal data we hold.

When and why we collect “special categories of personal data”

Certain categories of personal data, such as health data, financial data, biometrics, race, ethnicity, religion, health, sexuality or biometric data are classified as “special categories of data” or “Sensitive Personal Information” and benefit from additional protection.

We limit the circumstances where we collect and process these special categories of data.

Unilever sometimes collects data related to your health such as allergies, pregnancy or skin type to send you tailored ads and relevant promotions. Unilever only collects and uses this personal data where you have provided us with your consent for us to do so. In some instances, you may have requested services or products that do not directly involve the collection of any special categories of data, but may imply or suggest your religion, health or other special categories of data.

To illustrate circumstances where Unilever collects and processes special categories of data we have provided the following examples:

Unilever collects expectant mothers’ due dates in its Zwitsal or Baby Dove newsletter sign-up page. It may also place cookies on the sign-up page which capture this information too. This data is then used to create an audience of expectant mothers to receive online advertising from relevant Unilever brands. For more information on Unilever’s profiling activities, please refer to the relevant section;

Similarly, Unilever collects personal data related to consumers’ allergies to provide consumers with ads and promotions for products which are relevant to their needs.

How do we protect children’s privacy?

We understand the importance of taking extra precautions to protect the privacy and safety of children using Unilever products and services.

Most of Unilever’s websites are designed and intended for use by adults. Where one of our websites is intended for use by a younger audience, we will obtain consent from the person with parental responsibility before we collect personal data where it is required by applicable laws and regulations (the age at which consent is necessary varies from Country to Country).

If you are a child under the age where parental consent is required in your Country, you should review the terms of this Privacy Notice with your parent or guardian to make sure you understand and accept them. If we discover that we have collected personal data from a child without consent from a parent or guardian where such consent should have been obtained, we will delete that personal data as soon as practical. Access to certain parts of the Unilever’s websites and/or eligibility to receive prizes, samples or other rewards are generally limited to users over a certain age.

We sometimes use your personal data to carry out age verification checks and enforce any such age restrictions.

We collect, process and disclose your personal data only for specific and limited purposes. For example, to process your payments, to assess and handle any complaints, to develop and improve our products, services, communication methods and the functionality of our websites, to provide personalised products, communications and targeted advertising as well as product recommendations to you.

We also create profiles by analysing the information about your online surfing, searching and buying behaviour and your interactions with our brand communications by building segments (creating groups that have certain common characteristics) and by placing your personal data in one or more segments.

Additionally, Unilever processes your personal data also using automated means. An automated decision is a decision which is made solely by automatic means, where no humans are involved in the decision-making process related to your personal data.

We collect, process and disclose your personal data for the following purposes:

To process your payments, if you purchase our products, to provide you with your order status, deal with your enquiries and requests, and assess and handle any complaints;
To process and answer your inquiries or to contact you to answer your questions and/or requests;
To develop and improve our products, services, communication methods and the functionality of our websites;
For the purposes of competitions or promotions that you have entered;
To communicate information to you and to manage your registration and/or subscription to our newsletter or other communications;
To manage our everyday business needs regarding your participation in our contests, sweepstakes or promotional activities or request;
To authenticate the identity of individuals contacting us by telephone, electronic means or otherwise;
For internal training and quality assurance purposes;
To understand and assess the interests, wants, and changing needs of consumers, to improve our website, our current products and services, and/or developing new products and services; and

To provide personalised products, communications and targeted advertising as well as product recommendations to you.

When we collect and use your personal data for purposes mentioned above or for other purposes, we will inform you before or at the time of collection.

Where appropriate, we will ask for your consent to process the personal data. Where you have given consent for processing activities, you have the right to withdraw your consent at any time.

In some cases, we rely on legitimate interest for processing your personal data. A legitimate interest could exist for example, when you sign up for a loyalty scheme with one of our brands and we use the personal data collected to conduct data analytics to improve our products or services. This ground will only be used where it is necessary to achieve a legitimate interest, for example to assist in the performance of a contract, or to optimise a service, and does not outweigh your rights as an individual. This legal basis will only be relied upon where there is no less intrusive way to process your personal data. We can assure you that if legitimate interest is used as a ground for processing your personal data, we will keep a record of this and you have the right to ask for this information.

We process your personal data to perform a contract to which you are or will be a party. For example, we need to process your personal data to deliver a product or a service you bought, to allow you to take part in one of our competitions, or to send you samples that you have requested.

We also process your personal data when we have a legal obligation (e.g., tax or social security obligations) to perform such processing. For example, a court order or a subpoena may require us to process personal data for a particular purpose, or we may be compelled to process personal data to report suspicious transactions under the local anti-money laundering rules.

Profiling

Unilever uses your personal data to build profiles. We create profiles by analysing the information about your online surfing, searching and buying behaviour and your interactions with our brand communications by building segments (creating groups that have certain common characteristics) and by placing your personal data in one or more segments. These segments are used by Unilever to personalise the website and our communications to you (such as showing relevant content to you when you visit our site or in a newsletter to you), and to display relevant offers and advertisements from the Unilever brands on the Unilever sites, and via third-party websites. The segments can also be used for third-party campaigns on the Unilever sites. Unilever profiles your data where you have provided consent for us to do so; for example, accepting the setting of cookies on your browser online or signing up for email newsletters from one of our brands.

You can withdraw your consent to prevent your personal data being used this way at any time using the manage cookies section of our Cookie Notice or unsubscribing to the use of your email address if you have logged into one of our websites or signed up to any marketing newsletters.

By way of example –

Unilever collects data, with your consent, from:
- Our websites about what you view and the way you interact with our content;
- Our digital display advertising that we serve to you on social platforms and other publisher’s websites; and
- Forms you fill in online and send to us about what your interests are.
We also track the products you buy when you click on one of our display adverts and go on to purchase something from a selection of our retail partners.
If you have asked to receive emails or SMS communications from us, we track whether you open, read or click on the content to see what you are interested in so that we can give you more content that we think you are more likely to enjoy.
We use this data to profile your likes and dislikes. For instance, if we see that you are regularly viewing Vegan recipes on our “Recipedia” website, and you have opted in to receiving emails from us, we might give you an update on the new Vegan recipes that have just hit the site for your interest, or we may tailor our web content when you visit towards things we think you’ll be most interested in.
Based on this profile information, we may also give you advertising that we think you will like and want to see as you view content from us or from our network of publishers that we advertise with. Sometimes, with your consent, we may use your current location to serve advertising to you that is to do with promotions or events that are happening nearby that we think you might be interested in.
We may also use information you have provided to selected third-parties and consented to be shared, like your age, gender, life stage, lifestyle and wider interests to identify people who we think will have similar interests to you and who we believe will be interested in similar advertising.

Automated decision-making

In some instances, Unilever processes your personal data using automated means. An automated decision is a decision which is made solely by automatic means, where no humans are involved in the decision-making process related to your personal data. For example:

Unilever uses game simulations of science-based behavioural assessments and data science techniques to assess prospective employees. Candidates are required to play a set of games and the behavioural patterns exhibited during gameplay are assessed by a Unilever customised algorithm to predict the candidate’s potential for a specific role. This algorithm is regularly tested to ensure it remains fair, effective and unbiased.

We will not make decisions based solely on automated decision making that have significant impact on you. If we do so we notify you and provide you with clear information about our decision to rely on automated processing to make our decision and our lawful basis for doing so. For example, Unilever processes your personal data using automated means only if it is necessary for the entering into or the performance of a contract with you, or when you have given your explicit consent.

You have the right not to be subject to a decision which is based solely on automated processing and which produces legal or other significant effects on you. In particular, you have the right:

to obtain human intervention;
to express your point of view;
to obtain an explanation of the decision reached after an assessment; and
to challenge such a decision.

· To follow your instructions;

· To comply with a legal duty; or

· To work with our agents and advisers who we use to help run our business and services.

Your data may also be retained so that we can continue to improve your experience with us and to ensure that you receive any loyalty rewards which are due to you.
