- 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

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.

Secret to Stronger Strands Shampoo
Hair Type Straight Hair
My college daughter is loving this product. She has used the Redken Extreme (strength repair) and liked it before so this line was definitely something she wanted to try. She can't wait to see how this product will strengthen and help with length because we know Redken products do what they say they'll do!
Not for me
Redken products. This one however fell really short for me. Unfortunately it made my hair feel very processed, dry and much like brushing through a ratted barbies hair. It did the samd to my daughter.
Made my hair dry and tangled hair- Dont buy
Hair Type Straight Hair
I have extra long hair, to my hips, and is thin, somewhat wavy. I was looking for a new shampoo because my old one changed and the reviews were no longer good with new formula. I was recommended this shampoo by an Ulta employee. She was nice and for what I asked of a shampoo, this should have been fine. I was my hair 2-3 times a week. I used this shampoo three times and after each time, my hair became drier and drier. By the third time, the ends were getting so tangly after a shower that I was losing hair after brushing and my scalp was so dry that my hair felt straw like. Three strikes you're out. I wasn't going to keep using this shampoo because it was damaging my hair with every wash, and that's even with using extra hair oil to try and combat it. I switched to a new shampoo and after one wash, my hair is already feeling a bit better. The ends weren't tangly after a wash, my hair wasnt as straw like and my scalp wasn't dry. And that's just after one wash. The new shampoo is EVA NYC H2 WHOA! Hydrating shampoo.
hair growth then LOSS
I am very torn on this line. I started the shampoo and conditioner about a year ago. For 6 or 7 months I noticed all my shedding stopped and hair got thicker. Now out of nowhere I started shedding drastically and it's from the root not breakage! My hair is drastically thinner and it's not letting up. I thought it could be TE but now that I'm reading all the bad reviews I'm wondering if it's this shampoo and conditioner!! I stopped using this but is this like rogaine? Will it get worse if you stop it?
It's okay but theres better options !
Bondi Boost is amazing does the same thing and your hair won't fall out as much. This shampoo got my hair long but it cost me my hair thickness
