  • ★★★★★ Leaves My Hair Stronger and Healthier
Size: 10.1 Fl Oz (Pack of 1)
I’ve been very impressed with this shampoo. It cleans gently while leaving my hair feeling soft, strong, and refreshed. The biotin-infused formula lathers well, rinses out easily, and helps my hair look healthier and more manageable. My hair feels stronger after each wash, with less breakage during brushing. The quality is excellent, and a little goes a long way. I would definitely purchase this shampoo again. ... show more

  • Love it!
Size: 10.1 Fl Oz (Pack of 1)
This is an amazing shampoo. I got a HORRIBLE haircut a few months back. It was incredibly short. My hair was chin length all around. I was mortified. I saw many videos recommending this shampoo to help my hair grow quickly so I decided to try it out. OH MY GOSHHH my hair grew so much and it's so healthy! My hair was chin length in march and 4 months later it's shoulder length! (Ive gotten a few trims for maintenance.) Not only that, it smells great and my bottle is looking like itll last another 4 months! This shampoo combined with some scalp oiling will have your hair growing soft and FAST! ... show more

  • Good for nourishing your hair
Size: 33.8 Fl Oz (Pack of 1)
My daughter lives Redken shampoo. She's got 3b hair and it makes her hair silky and smooth. It's even helped nourish her hair so she doesn't have dead ends. Fragrance is light but smells good.

Love this shampoo. All I use anymore. Leaves my hair soft and feeling moisturized. Has helped my spilt ends almost dissappear after using it for a few years now. My hair has grown more than it ever has using this shampoo and conditioner! Will always keep buying.

  • BUY IT! WORTH IT.
Size: 10.1 Fl Oz (Pack of 1)
Works !!! This stuff really does work ! Look first picture is from march. We are in may now. That’s two months. I will continue to buy this until I get my desired length. I will say that my hair gets drier than normal with this product so I don’t use it everyday. I use this about 1 time a week. I try not to wash my hair but if I have to I’ll use a more moisturizing one, it makes my scalp itch because there really isn’t any moisture. It does make my waves pop, this is the second day I washed my hair the day before. It does give my hair a nice shine. ... show more

  • You will love Redkin Products!
Size: 33.8 Fl Oz (Pack of 1)
Redkin has outstanding products. I love their shampoo and conditioners! It’s great for colored hair. No astringent chemicals that would make your hair brittle or dry. I have been a Redkin enthusiast since 1970’s.
