Small but mighty, each pack contains at least four applications. Easy to squeeze, our packs are 77% lighter than a container of the same size and perfectly sealed for a fresh application each time.


Apply to wet hair and leave in 3-5 minutes. Rinse thoroughly. 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.

Use once weekly in place of Biolage FiberStrong Conditioner. Recommended for mechanically damaged, fragile, over-processed hair.
