Smoothing Treatment The Best Keratin GK Hair

Difficult to tame your damaged and frizzy hair every morning? GK Hair The Best smoothing treatment is for you. This smoothing treatment has been developed to respond to the problems of difficult hair thanks to its ultra-protein formula based on superfoods. However, suitable for all hair types, the GK Hair smoothing treatment offers a boost of nutrition and shine to dull and sensitized hair.

This intense treatment must be applied to perfectly clean hair and sealed with heat (hair dryer or straightener). It is considered one of the best keratin treatments and provides results that last up to 4-6 months. Styling time is cut in half. It is safe to use on colored hair and does not alter color.

GK Hair smoothing owes its effectiveness to its formula. Rich in superfoods, it contains:

  • Juvexin: (a keratin-based anti-aging protein blend) protects your dry, brittle and color-damaged hair from harsh environmental elements.
  • Natural Seed Extracts: Moisturize, leaving hair nourished and revitalised.

Formulated without sulfates, parabens, phthalates, DEA, TEA or gluten.

Application :

  • Start by making 2 pH+ GK Hair clarifying shampoos. Thus, the hair is rid of impurities and prepared to receive the Juvexin treatment. Towel dry the hair and brush it.
  • Apply The Best by parting the hair ½ inch each and use the application brush to apply the smoothing product to each section. Be careful not to apply the product on the scalp! Make sure to stay ¼ inch from the scalp with the brush. Be generous when applying the product as the hair must be fully saturated for the treatment to have an optimal effect.
  • Cover the hair with a plastic cap. For fine, wavy hair, leave on for 40 minutes. For thick, curly hair, leave on for 60 minutes for best results.
  • Rinse with lukewarm water until the products are clear on the hair. If hair is over processed or red, wash with GK Moisturizing Hair Shampoo focusing on ends to remove excess product.
  • Use GK Hair Deep Conditioner, leave on for 5 minutes then rinse.
  • Blow dry hair directly on high power with a round brush using sufficient tension to smooth hair until 100% dry.
  • Section hair and GK Hair 400 degree titanium flat iron straightener. If the hair is overprocessed, straighten at 375 degrees, lower the temperature further if the hair is very weak and damaged; especially towards the ends of the hair. Pass the straightener approximately 2x to 4x on each GK Hair conditioner enriched with Juvexin to maintain and maintain the results of the treatment.

J'ai utilisé d'autres marques de lissage brésilien dont "Coacoa brasilis" qui a flingué mes boucles... Elle ne sont jamais revenues. J'ai utilisé global Kératine, je suis satisfaite, mes cheveux sont un peu sec après le premier lavage mais je pense que c'est à cause du shampoing clarifiant. Et par expérience cette sécheresse se dissipe quelques shampoings après. Je reviens toujours à global kératine. Je suis plutôt satisfaite, surtout que le lissage n'est pas désagréable à réalisé car il n'y a pas de fumés nocives ou toxiques lors du lissage.
