Multi-use deep treatment hair mask for mechanically damaged, fragile, over-processed hair.
Paraben free, Sulfate free
Apply to wet hair and leave in 3-5 minutes. Rinse thoroughly. For extreme damage, place under heat for 3-15 minutes. Use once weekly in place of Biolage FiberStrong Conditioner. We recommend that you use the Biolage Advanced FiberStrong Deep Treatment after cleansing with Biolage Advanced FiberStrong Shampoo to target hair that may be fragile and prone to breakage.
Small but mighty, each pack contains at least four applications.
Tip! No need to use conditioner our highly concentrated formulas result in hair feeling more manageable and easier to detangle.
Avoid contact with eyes. Rinse immediately if product comes into contact with them.
