Flex has been my favorite since I was a girl. It's wonderful to know I can still get the great product at a reasonable price. Protein shampoos like Flex are hard to find, and my stylist says they are better for your hair than ones with oils, waxes, or heavy conditioners.

I have used this shampoo for over 20 years. It's THE best ever and I usually buy it by the case. Nothing compares and I have tried. No salon brand or anything expensive can come close. It's so clean and gentle and leaves my hair soft and shiny. I have shoulder length, thick hair and I always get compliments on how soft it is. The only other shampoo I use is Aveda for color treated hair, and I only use it for a short time, then switch back to Flex moisturizing. I do not use the conditioner however. Instead I use the conditioner that I get in the color kits. (I do my own color at home- Loreal Excellence) I can not say enough good things about Flex. 20 years of the best hair to prove it.

Keeps my hair clean for days and smells good!!

Shampoo is shapoo, but Flex does a fine job and is the least expensive shampoo on the market. Unbeatable combination!

I used to use Flex shampoo and have not been able to find it! My boyfriend always used to say that my hair smelled "So good" I am so happy that I found it again!!! I had to buy through the mail because I can't find it on the shalves in the store. I purchased five and am thrilled!!

I use Flex Moisturizing Shampoo & Conditioner everyday. It's the best smelling shampoo out there! I get compliments all the time on how shiny and soft my hair is and how good it smells. I've been using it since I was a little girl. If I were asked to describe Flex in a word - FRESH!

This is a classic that can't be beat! No matter the brand of shampoo & conditioner I try- both drugstore brands and pricier salon brands- I always come back to this. It leaves my hair just as shiney and soft as more expensive products. But it's the smell that is my favorite and I get complements from family & friends on how wonderful my hair smells! It's gotten harder to find the my local stores. I hope drugstore.com will always keep it in stock!

I have purchased so many other shampoos to try and always come back to Moisturizing Flex. My bleached blonde hair just loves it. People complement its beauty and ask to touch it. My last bottle of shampoo has emptied quickly so I think a male relative is also using it instead of Pantene.

Not impressed. This product contains sodium lauryl sulfate, which is very drying to some types of hair (mine included). It's cheap and smells fresh and cleans well, but I'm frizzy after I use it.

Great cheap product! Very good on the scalp, too! I love clear shampoos, pearl ones are very itchy! This one has a great smell, too!
