I recently had the pleasure of trying out a new hair mask, and I must say, it exceeded my expectations in many ways. With dry and damaged hair, I'm always on the lookout for products that can provide deep nourishment and repair. This particular hair mask did just that and more. Here's my comprehensi...

Amazing !!!

From the first wash, I could feel the difference in my hair—it's so much softer, shinier, and smells amazing!
This alone helps hair grow

My hair was cut too short to my liking - basically chopped off and since it hasn't seem to be lengthening. I bought the Redken Extreme Length products and it is the mask that seems to make the difference.
Seems to Work
It's March 2026, and I've been using this product almost weekly since November 2025. My last trim was mid-December 2025, and I usually need a trim every 4-6 weeks because my ends start splitting and drying out, but they look and feel good. I wouldn't say this product helps your hair grow faster, but it definitely keeps it healthy, so you can retain the length you've grown. Try it!
Read if you have Ktip extensions!
I 1st asked if this line was ok for ktip extensions and i was told yes (by Redken). I will say I definitely noticed it works BUT its not good for the bonds. Strands from your extensions will stary to come out like crazy!
