Process for Cysteine treatment

If you are looking for a relaxing break and want to be pampered, go for a cysteine hair treatment, which lasts about three hours and will provide you with an excellent well deserved soothing break!

  1. The first stage is for an expert to assess your hair type (texture, length, volume, fizziness level, and so on) and tailor a cysteine treatment for you (time, amount of cysteine utilised, and so on).
  2. The expert will next carefully rinse your hair to remove any debris, pollutants, or excess oils.
  3. The formula is then applied to semi-wet hair in the following stage. This step guarantees that the cysteine has a better chance of penetrating.
  4. After that, the hair is blow-dried fully. The expert will next break off small parts of hair and administer cysteine equally on the hair roots and throughout the hair.
  5. The hair is left for 45-60 minutes after it has been covered completely with the mixture (Usually, not a single strand of hair would be left by the professionals!). Letting it to rest improves outcomes by giving the roots and the hair time to absorb all of the nutrients and protein.
  6. Following that, the hair is heated, with an ironing process and mild blow dry that emphasises the sleek look even more. Heat activates cysteine, therefore this step is important.
  7. Finally, the hair is cleansed again with deep conditioner and shampoo that is designed specifically for treated hair. When the hair is dry, damaged, wavy, or frizzy, you will notice that it is no longer damaged, dry, frizzy or wavy. Instead, it’s all straight, silky, shiny, healthy and bouncy.

Tip: If you get bored or agitated during your cysteine treatment, bring a phone with some decent movies and a set of headphones with you.
