Great for post-treatment hair

Brian L. · 2026-03-22 · Verified purchase

My wife got this for me to use after getting my hair lightened, and it really works. My hair feels a lot stronger and less frizzy than it usually does after chemical treatments. Definitely helps with the integrity of the hair.

★★★★☆

Helps with dry, damaged hair

Taylor T. · 2025-11-21 · Verified purchase

My hair gets very dry and brittle from styling. This treatment has improved its texture and reduced some of the dryness. It's effective, but the results aren't incredibly dramatic for my level of damage after just a few uses, so I'll keep using it.

★★★☆☆

Minor improvement in texture

Adam L. · 2026-05-27 · Verified purchase

My hair feels slightly softer, but no dramatic difference in strength after consistent use.

★★★★☆

Effective for strength, small size

Jorge F. · 2025-10-21 · Verified purchase

This product does make my hair feel stronger and less prone to breakage, which is exactly what I needed. The only drawback is that the 3.3 oz bottle is quite small, so I have to repurchase more frequently than I'd like. It performs as promised, though.
