- Q
is this product good for high porosity hair?
- Asked by angie
- Official Answer By Redken - BEHi there! Thank you for reaching out about our Extreme Length Shampoo For Longer, Stronger Hair. That is a great question! Yes, Redken Extreme Length is an excellent choice for high porosity hair. High porosity hair often has gaps in the cuticle, which causes it to lose moisture quickly and break easily. Our Extreme Length Shampoo is infused with Biotin and Soy Protein, which help to 'fill' those gaps and reinforce the hair fiber from the inside out. This strengthening action is exactly what high porosity hair needs to reduce breakage and successfully reach longer lengths. Pro-Tip: Because high porosity hair also craves intense moisture, we recommend following your shampoo with the Extreme Length Conditioner and a weekly treatment like our Acidic Bonding Concentrate Mask to lock in that hydration and seal the cuticle for maximum shine!Was this answer helpful to you

My Fave!!
About 9 months ago I was sent this shampoo, conditioner and leave in treatment to review by a third party company. I have to admit, the first thing I noticed was the scent. It's marvelous!!

Scent is wonderful, overall product not as much
I received this product to try for free in exchange for sharing my opinion about it. I have fine hair that lacks volume, as well as certain pieces that don't really seem to be growing at all, so I was very excited to try this product.

Hair Type Very Curly Hair
This is very good free my hair within a month of using it
Yes, I would buy Extreme Length Conditioner again
Hair Type Straight Hair
I would definitely buy Extreme Length Conditioner again. A good product. I have fine thin hair, this works well for me. Thank you.
This shampoo is my new holy grail.
Im in my late 20s, and Ive been struggling with hair loss and thinning for a few years. My hair now breaks very easily and is very prone to heat damage. Ive tried quite a few "growth" shampoos, and the extreme/extreme length line is the only one thats actually shown results. I have been using this shampoo consistsntly for the last 3 months, and tonight I found about 20 strands of new growth on my crown and feel like crying with joy! My hair also feels stronger and softer once I added the conditioner to my routine. The only thing I would suggest, is making sure to take a break from this shampoo at least once a week and use a clarifying shampoo. With this combination and regular trims at a salon, I promise you will see results!
I would not buy this product again
