- Q
Can i use it everyday when washing my hair and doesit promote hair growth?
- Asked by iv
- Official Answer By Redken - BEHi there! Thank you for reaching out about our Extreme Length Triple Action Treatment Mask. That is a great question! When it comes to the Redken Extreme Length Triple Action Treatment Mask, achieving the right balance for your hair is key: For Everyday Use: This mask is an intense, highly concentrated reparative treatment with our Biotin and Niacinamide complex. We typically recommend using it 2-3 times per week or as a replacement for your conditioner as needed. Using it "every day" may lead to protein-moisture imbalance, making your hair feel a bit too stiff rather than soft and bouncy. For Hair Growth: While our Extreme Length range is specifically designed to promote longer, stronger hair, it does so by reducing breakage by up to 81% (when used as a complete system). It focuses on the hair’s health and resilience, which helps you "retain" that length as it grows. It does not "stimulate" new growth from the scalp, but it is the best way to see the "pop" of length you've been looking for by keeping the hair you have healthy and strong!Was this answer helpful to you

Excellent for the hair!
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...

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!

I have a lot of hair and this felt so good in my hair My hair feels really nice afterwards
moisturized my hair but burned my scalp
it felt cooling at first but then my crown around my head started to burn but left my mids to ends feeling moisturized so maybe be cautious about putting it on your scalp
