Description: Redken's Strength Builder Plus Extreme Mask is a deep conditioning treatment specially formulated for weakened and brittle hair. Enriched with proteins, this mask works deep down to restore and strengthen the hair fiber, reducing breakage and increasing hair resistance. Thanks to its RTC complex, this mask acts on all three levels of the hair (root, length, and tip) to provide complete and revitalizing care. Used in conjunction with the Extreme shampoo and leave-in conditioner, it reduces breakage by up to 75%, leaving hair restored, strong, and naturally shiny. Furthermore, this mask respects the hair's pH and has been dermatologically tested.

Formulated with RTC technology and proteins such as soy, arginine, and Sepicap, this mask strengthens roots, structures lengths, and restores the ends of weakened, brittle, damaged, dry, and sensitized hair. Furthermore, its Fortifying Complex technology rebuilds the hair's protective lipid barrier and smooths the cuticle. Thanks to its 250ml size, this mask offers extended use for lasting results.

For optimal application, it is recommended to apply the Redken Strength Builder Plus Extreme Mask to previously washed and towel-dried hair. Distribute it evenly through the lengths and ends, then leave it on for 5 to 15 minutes before rinsing thoroughly. Give your damaged hair the deep repair treatment it needs with the Redken Strength Builder Plus Extreme Mask.
