Girls with curly hair, we know you’re looking to tame those curls although we totally think bouncy curls are a matter of pride. If you think otherwise and wish to straighten your curls, we’re here to help. No, we’re not telling you that the solution lies in a flat iron—straightening that lasts only until the next wash. To achieve longlasting straightening, you need to choose between a Cysteine hair treatment or a Keratin treatment. Wondering what we’re talking about? Take your pick after reading about them…


1. What is the Cysteine straightening treatment?

What does it do?

A Cysteine hair straightening treatment is perfect for those who have extremely frizzy and unmanageable hair as it strengthens your hair roots. In this treatment, the straightening wears off very naturally without looking overtly obvious. However, it is a semi-permanent treatment that lasts only for three months.


2. What is the keratin straightening treatment?

What is the keratin straightening treatment?

In this treatment, your hairstylist will apply keratin by infusing it into your hair through creams and then going in with hot flat iron to absorb the keratin into your hair. It takes almost 90 minutes depending on the length of your hair.

This treatment is affordable compared to Cysteine and leaves your hair smooth and shiny. So if you want to go a notch higher than hair rebonding, this could be the next step. However, it can cause health issues as Keratin straightening includes the use of formaldehyde, which when inhaled can be rather harmful.


3. Who can get cysteine treatment for hair?

Who can get cysteine treatment for hair?

While everyone craves smooth, silky, and nourished hair. But, while some can get it with ease and minimal treatment, some have to dish out more effort and money. In this case, a cysteine treatment is a boon for those who have curly and frizzy hair. Further, if you are someone with dull and damaged hair, this treatment can give your hair a boost of health. Cysteine treatment is known to reduce curls by almost 60 percent. So be ready to lock your curls straight when you go for this.

A word of caution, though. If you have recently got your hair coloured, it is strongly advised that you wait at least two months before going for the cysteine treatment. Further, if you have thin hair, this treatment is a strict no go as it will further flatten the hair and reduce its volume.


4. Cysteine treatment for hair: Pros and Cons

Cysteine treatment for hair: Pros and Cons

While cysteine treatment for hair looks attractive and has many benefits, there are certain disadvantages as well. Let’s take a look at them.

Here are the pros of this treatment:

  • Safer than keratin
    Cysteine treatment is known to be quite safe as compared to keratin. In fact, this can even be used when you are pregnant. Of course, consult your doctor before you go that route.
  • Better than keratin
    This treatment is also better than keratin and most other hair treatments.
  • Has longer effects
    Cysteine treatment has long-term effects in the sense that the new hair that will grow will not be curly. Thus, the new hair will look exactly like the treated hair, giving you more longevity.

Here are the cons of this treatment:

  • More expensive
    Obviously, with all the pros that it comes, the cysteine treatment is by far one of the most expensive hair treatments. This, of course, can be a con for many.
  • Does not last long
    Despite the promising stunning effects and longevity in the form of new hair growing like the treated hair, this hair treatment does not last beyond 4 months. For the price you pay, this really is a short period.

5. FAQ on cysteine treatment for hair

FAQ on cysteine treatment for hair

Q. Can you oil your hair after cysteine?

A. Avoid oiling too much after the treatment. The reason is that too much oiling can lead to a build-up, which counters the effects. Also, this will further cut down the longevity of the treatment.

Q. Can we do cysteine treatment at home?

A. There are quite a few cysteine treatments, shampoos, conditioners, and masks available. You can use those to achieve salon-like results at home. Also, in case you do not get cysteine shampoos and conditioners, pick any sulfate-free ones and get the cysteine treatment at home. Use as per the instructions.

Q. What is better keratin or cysteine?

A. Cysteine is a better treatment because it not only lasts long but also does not have any chemicals such as formaldehyde or its substitutes. On the other hand, the only argument in favour of keratin is that it is cheaper.
