I used this years ago and have just rediscovered it. I love the smell and how strong it makes my hair feel.

After reading the reviews here, I was very excited to order a bottle of Flex Shampoo, since I loved it as a teen in the early 1970s. Unfortunately, this product is nothing like the original. The original Flex was a very thick shampoo that actually smelled like balsam - and I work as a scientist using actual balsam to make microscope slides, so I know what it smells like. This does not smell like balsam or the original Flex AT ALL. It doesn't smell bad, it just smells different. This shampoo cleans well but it's no better than many other shampoos out there, and if you're hoping to get the original product, this ain't it. However, for the price, it is a decent shampoo.

I have been looking for this product for months and months, all to no avail. On a whim, I looked it up on the internet to see if it was still available. I was so excited when I found it, I ordered two bottles of each - shampoo and conditioner. Thank you so much for bringing my hair back to life!

Bought as a gift for lady with oily hair who washes hers every day. I use it twice a week and find it adds body and shine my hair did not have before.

This is my favorite shampoo, it leaves your hair shiny and lightweight. I have oily hair and have to wash my hair daily other shampoo leave my hair dry or weighed down but this one does not. I wish I could buy it at my local drugstore I totally recommend it. I get a lot of compliments on my hair when I wash my hair with Flex. It's the best shampoo ever. I can't believe it's so cheap, you get top quality and a low price.

This shampoo does indeed add volume and can't be beat for the price. One should note that the smell is hearty, a wintery, spicy scent. It's full-bodied. Let's put it that way. So if you enjoy light floral fragrances, this might not work for you.

I use Flex Extra Body for quick shampooing in a hurry and for cleaning off other shampoo brands. It smells great, adds some body and rinses clean. It doesn't moisturize enough to keep my hair from sticking straight up however. I would use a conditioner if I were going out after using it.

I had used this for a very long time, then it disappeared. I have tried to find something I was happy with, but nothing could live up to "FLEX" !! I was so HAPPY to find it again, as it is the complete package. I just love it !! Sure hope it stays forever. VERY SATISFIED CUSTOMER !!

I shampoo daily so Revlon Flex is perfect for me. Very good for the hair. Smells great.

I still can't believe how cheap this stuff is, mostly because it works so well. Flex leaves my thin, fine, straight hair (treated with non-permanent color) soft, fluffy and shiny.
