Grey Hair: Causes, Treatment Options and How to Prevent Premature Greying

Amidst 100 problems, if grey hair is one then we feel you. Here are the causes that you must take note of.

• Melanocyte decline: Your hair follicles contain pigment cells called melanocytes, which produce melanin, the stuff that gives hair its colour. Over time, these cells naturally slow down and eventually stop producing pigment altogether, leaving strands to grow in grey, silver or white.
• Genetics: Honestly, this is the big one. If your parents greyed early, there's a solid chance you will too — it's largely written into your DNA long before lifestyle even gets a say.
• Ageing: As a general (very loose) rule, many people start noticing greys somewhere in their thirties, though this varies wildly by ethnicity and genetics.
• Oxidative stress: Free radical build-up within the hair follicle can damage melanocytes over time, accelerating the greying process beyond what your genes alone would dictate.
• Hydrogen peroxide build-up: Yes, really — your body naturally produces small amounts of hydrogen peroxide, and as we age, enzymes that usually break it down become less efficient, allowing it to bleach hair from the inside out.

Premature grey hair can be caused by several reasons. Some of them are:

• Genetic predisposition passed down through family
• Chronic stress and elevated cortisol levels over long periods
• Nutritional deficiencies, particularly vitamin B12, iron, copper and vitamin D
• Underlying health conditions, including thyroid disorders and autoimmune conditions like vitiligo
• Smoking, which is strongly linked to earlier onset greying
• Harsh chemical treatments and excessive heat styling that stress the scalp and follicles

If you're noticing grey strands appearing significantly before what's typical for your family or ethnicity — think before your mid-twenties for a lot of people — paired with thinning, dullness or a generally more brittle texture, that combination is usually your cue that something beyond "just ageing" might be at play.

Once melanocytes have ceased all pigment production for that one strand of your hair, chances are extremely slim that anything will change. However, in instances where early-onset grey hairs could be tied back to some form of nutritional deficiency or other health issues, targeting those conditions may help alleviate some of the premature greying and even coax some colour back into those strands (as has been documented).

So while this isn't magic, nor is it total fantasy, it's also important to acknowledge these aren't guarantees.

Here are ways to treat grey hair

• Targeted Serums

I can tell you that formulas intended for scalp health and pigmentation (such as my dear friend Indulekha Jatamansi Premature Greying Serum) focus more on nurturing the environment of your scalp, which relies upon your follicles, rather than promising some sort of 'dye'-ing magic happening inside your strands!

• Nutritional Correction

Supplement with what's missing if your bloodwork points to deficiencies — this has been proven to work well for some people in slowing down premature greying.

• Scalp Care

A regular scalp massage can increase the blood flow of your hair follicles, providing a better environment for the pigment-producing cells to work properly.

• Semi-Permanent or Permanent Colour

And whilst I can't tell you how glamorous this might be – sometimes this will be your best treatment when working through the underlying causes!

• Vitamin B12: Deficiency has been one of the most well-documented links to premature greying.
• Copper: An essential nutrient for melanin production. Low levels have been linked to greying in several studies.
• Iron: Supports healthy circulation to your scalp and follicles.
• Vitamin D: Plays a role in follicle health more broadly.
• Folate: Works alongside B12 to support healthy pigment cell function.
• Protein: Hair is largely made of protein, so your diet should be as balanced as possible (supplementing with one item doesn't make up for deficiencies elsewhere).

• Managing Stress: Chronic stress has been linked to accelerated greying due to oxidative damage. Make sure to include proper downtime in your life!

• Quit Smoking: There's no denying that smoking contributes to premature greying. So if you're a smoker, quitting may help slow down the process.

• Take care of your scalp: Excessive heat styling & harsh chemical treatments can create a stressful environment on the scalp. Try to reduce them as much as possible. Use a gentle hair cleanser and sulphate-free options.

• Go for a checkup: If your greying seems unusually rapid or occurs at a young age, you should get tested. It could indicate a hidden deficiency or condition.

• Use Sulphate-Free Shampoos
• Include a Nourishing Serum or Oil Treatment
• Avoid Heat Styling (Or At Least Use A Heat Protectant)
• Massage Scalp Regularly
• Be Consistent – Hair grows slowly! You need to try a new routine for a few months at least before seeing results.

If the grey strands appear suddenly or unusually early, along with symptoms such as fatigue, hair thinning, or patchy hair loss, you should visit a doctor/dermatologist immediately. This is crucial for ruling out thyroid problems, vitamin deficiencies, or even some immune system disorders.

Grey hair doesn't have to be a bad sign. In fact, sometimes our body does what it wants when it needs to! However, when we face premature greying, it's better to look after our overall health as grey hair can flag potential issues that might be addressed. While we cannot change genes, there are various factors that contribute to the issue and many things we can manage ourselves! So make sure to take the necessary precautions. And also, never fall under the impression that a serum alone can turn back time!
