Healthier hair!
This shampoo leaves my hair super soft after every wash. I feel like my hair has grown more since I started using them, and I’ve noticed way less breakage. My hair looks healthier and feels stronger overall. I’m really happy with the results and would definitely recommend it!

Made my hair feel and look great!
I purchased this a couple months leading up to my wedding. It made my hair so soft. I typically have very dry crusty curls, but it smoothed it out and seemed to help the volume. I would compare the feeling to a fresh hair cut. I’m not sure how much my hair grew, but I was pleased with my hair at my wedding!

Repaired my damage!
I just want to say that this product has grown my hair at an insane rate. For starters, I have been on a hair care journey for almost 6 months after taking out tape-in extensions and finding my hair at the worst state it’s ever been in. I have natural very thin hair so this didn’t help my already insecurity about that. It was Dry, brittle, noticeably see-through, and thinning. I knew it would take time to see results but kept trying. I started with the extreme repair and just recently made a switch to the extreme length when I saw improvements. I have been actively cutting my ends off to get rid of the dead ends from 6 months ago. I have been trimming regularly. My hair has returned to its thickness, is shiny, and grew my hair so long in just 5 months. I also use the redken blowout/thermal spray and redken acidic hair mask and leave in conditioner(not every wash). I am so thankful for finding this product. I never write reviews but had to just explain how thankful I am.

Great shampoo
The product is good, lightweight and light smell. You Don't Need much to get your hair clean. I don't know if it's a distributor thing nor seller thing but it was not packaged well to protect it from bursting open while in transit. That should be revisited.

Moisturizing and Lightweight
I highly recommend this shampoo! It has helped product build up on my scalp as well as regular dandruff! My hair is extremely soft and stays moisturized until my next wash! I usually wash every 3-4 days and I don’t get any excess grease build-up from this shampoo!

Buy it, you won't regret it!
I bought this (along w the conditioner) for my teen daughter in November and tried it. I loved it so much I just ordered myself a set! I'm growing my hair out, and this shampoo just makes my hair feel so lush afterward! Shiny look, smooth feeling, and my hair just seems so much more healthier. I highly recommend! No more stringy feeling after a day or two! Look and feel last for longer! And a little goes a long way, use sparingly.

Amazing!
Genuinely seeing so much difference in length and even hair length. Tho I do switch every other week so I’m not over using. This is a life saver. It helped my curls grow so much !! If you want your hair long and soon, get this girl 😭❤️

Se siente la calidad y la relación con el precio, tiene un aroma sutil pero bastante agradable y rico, he notado que mi cabello sí creció mucho más rápido (como dos centímetros en 1 mes) y bastante bien, no deja reseco ni grasoso el cuero cabelludo y se siente bastante suave en el cabello, lo utilizo en conjunto con un cepillo especial para dar masaje en el cuero cabelludo, tiene sulfatos; por lo que si acabas de salir de una decoloración, te recomendaría que primero utilices un shampoo enfocado en reparar tu cabello e hidratarlo, aún así, después yo lo comencé a utilizar y me deja el cabello súper lindo. Noté que me aporto también mucho más volumen, pero nada de frizz. Tardó un poquito en llegar pero en excelentes condiciones.

Wonderful, leaves my hair feeling great for days, and my hair feels very healthy with minimal shed. Friendly to coloured hair. After running out of this I purchased the 1000mL bottles from a local salon shop. You can add water to the remainder of your bottle to get all of the product out, though I had to pour it in from the top as the bottle is very difficult to take apart. You do not need a ton, about a quarter size drop and you should have enough for your roots. Shampoo foams up nicely, conditioner stays slick. Does not seem to cause me any skin issues and I have fairly sensitive skin and an acne prone chest/back. One note: product is unfortunately not cruelty free, but I have not been able to find a cruelty free product that compares.
