Product Benefits

A thermo-protecting blowdry and heat-styling cream designed to seal lengths and split ends.

This smooth gel cream protects the hair from heat up to 230°C to reduce breakage. Hair is strong, resistant and can grow longer while remaining healthy.

  • 8H of overnight nourishment, in combination with Bain Satin 2 + Masquintense
  • Provides easier detangling, avoiding pillow friction
  • Hair fiber is soft to the touch
  • Increases manageability of normal to coarse hair
  • Hydrates without weighing down on fine hair
  • Provides curly hair with definition

Rated 5 out of 5 by from Amazing products! I received this a week ago and it has really changed my hair, from dry and frizzy to smooth and luxurious! I reccomend this to all my friends, especially when they comment on my hair!

Rated 5 out of 5 by from This might just be the best product for my hair. I’m a 24 y/o male. I got this product free with an order. I didn’t use this for a long time and once I did, my hair was without a doubt the best in ages. It makes my hair smooth and silky without any frizz. Totally recommend it for after shower use.

Rated 3 out of 5 by from Not My Favourite Product from this Line I've enjoyed the Serum and Masque from this line but did not see the same results from this product. I found my hair more difficult to brush and I'm sure it offered some heat/styling protection but did not find it added anything to the length. I'm going back to Discipline for this one!

Rated 5 out of 5 by from Perfect for long hair Bought this last month and my hair looks much healthier. Simply apply before blow drying. I follow up with Serum Therapiste once dried
