Soupleliss Hair Finisher Nanocrystallization Spray & Heat Protectant — 250 ml

Give your hair an extra touch of mirror-like shine. Soupleliss Hair Finisher is a professional leave-in nanocrystallization spray designed to help protect hair during blow-drying and flat-ironing while creating a glossy, polished finish.

We recommend this finishing spray after nanoplastia, keratin treatments and hair botox services, before the final blow-dry, to add an extra protective film and enhance the hair’s mirror shine.

What it does

  • Creates a luminous, mirror-like finish with nanocrystallization styling care.
  • Helps protect hair during blow-drying and flat-ironing.
  • Helps smooth frizz and improve manageability.
  • Adds a soft, polished finishing touch after professional treatments.

Key active ingredients

  • Lisseline: helps control frizz, smooth the hair and enhance shine.
  • D-Panthenol: helps retain moisture and improve softness and flexibility.
  • Hydrolyzed Keratin: helps condition weakened lengths and improve manageability and resilience.

How to use

  1. Shake well before use.
  2. Spray evenly through damp hair before drying, without oversaturating.
  3. Leave in, blow-dry and style as desired.
  4. If using a flat iron, ensure the hair is completely dry first.

Our professional recommendation: apply after completing and rinsing the nanoplastia, keratin or hair botox treatment, before the final blow-dry, for an extra protective finish and mirror-like shine.

I received my hair straightener and yesterday I did my first keratin with the new hair straightener, it is just wonderful and magical, the result is really 2 times better than with my last hair straightener, although it is also professional and I thought it was good. It is a pleasure to work with your hair straightener, thank you so much for such a great product 🙏🙏🙏

Hair was not electrified at all and the shine was better and I smoothed my hair 2 times faster.
