What Is Cysteine?

Cysteine Hair Treatment Vs Keratin Hair Treatment

Cysteine complex is part of the Keratin group. Both the cysteine and keratin hair treatments are not much different from each other.           

Both are expensive and temporary. However, there are a few features which make cysteine treatment distinct. 

  • Cysteine hair treatment is free from chemicals which makes it safe for use even by pregnant women.
  • It does not contain formaldehyde or its substitute, which are present in most keratin treatment products.
  • It is considered a gentler treatment as opposed to Keratin.
  • It is so safe that even children who are above the age of 12 years can get it done.
  • Possible to do cysteine hair treatment at home versus visiting the salon every time you want keratin treatment.
  • It fades away easily without making it look obvious. (You won’t look like a mess when it wears off.)
  • The new hair won’t grow out to be curly or wavy after cysteine treatment. In other words, as your hair grows, you won’t see a difference between the new growth and the treated hair.

Who Can Get Cysteine Hair Treatment?

It is a treatment recommended for hair which has become dull and damaged with the regular use of harsh chemicals.

If your hair is limp and lifeless, cysteine treatment is the way for you.

This hair treatment has proven itself as a boon for women with curly and frizzy hair. It reduces about 60 percent curl volume of ethnic hair and 70 percent curl volume on Caucasian hair. Overall, it is able to reduce curls by 50 to 60 percent.

However, cysteine treatment for thin hair is not such a good idea. Women with thin hair should avoid this treatment as it can make your already thin hair look even flatter.

If you have recently coloured your hair, then you would have to wait for at least two months before getting this treatment.


As part of the treatment, you are advised cysteine complex shampoo, conditioner and serum.  Also, you’ll have to use it for the next few months.  And you cannot wash or even tie your hair for the next two days after getting this treatment.

Other precautions that you must take:

  • Use cysteine based serum to elongate the life of the treatment
  • Avoid swimming for at least a month
  • Avoid chemical treatment
  • Get hair spa at least once a month
  • Stop the use of henna

  • Prevent frequent washes. Shampoo thrice a week.
  • Avoid metallic dyes
  • Do not oil your hair

Don’t get intimidated by the number of things you have to avoid. The results of cysteine treatment will be worth all this effort. But you would have to prepare yourself for this months’ long commitment.

Overall, cysteine treatment will work wonders for your hair whether they are dull and damaged or curly and frizzy. Before taking a decision, give it a serious thought, consider all the facts, and consult your stylist. If you feel you can commit to this treatment, then you are ready.
