i find this to be a very effective shampoo! always felt my hair has been strong and soft but i will say that the “equate” brand of this shampoo works pretty much the same and is always like $2 less. very dense so you don’t need to use a lot, it can stretch for a while

Have used this for years and loved it. Was able to wash my hair 3 times a week and it looked good every day. The new and improved is definitely not an improvement. It leaves my hair dry and frizzy the first day and flat and greasy the second. I don’t even understand how that’s possible! Guess it’s time to find another brand.

I like the scent of this shampoo. I always felt that my hair was thoroughly cleaned. It lathers well and doesn't require much product. Although I never really noticed a difference in the strength or length of hair while using. Overall I probably wouldn't buy again.

I am so glad I took a chance on this product. I love the difference it has made in my thin hair to appear much thicker and full as promised. I usually go for unscented but this has given me no problems at all. You use such a small amount the size of a dime, so this should last a good while in the small size.

I have tried many shampoos from this company because well they work... I decided to this shampoo and conditioner because I liked what its suppose to do to my hair... while I like the feeling of my hair and bit of volume it adds... the smell is HORRID! I am so mad at myself for not smelling it before I purchased it. I just thought I was gonna like the scent since all their products smell like heaven... this smell like mothballs... or like a attic that hasnt been aired out for years!! I will NEVER buy this shampoo and conditioner again. I will and buy the other ones they have but this one.. smell AWFUL!

I think this product really does make my hair look fuller and the scent is amazing but I think it leaves my hair a little bit opaque and I want it to be healthy shiny so I'm looking for something that gives me both benefits in one, I don't think I'll repurchase this.

I initially bought this because I loved the smelled of it. I then quickly found out that not only does it smell great, but it makes your hair feel thicker! I’ve used shampoos like this that have this effect but makes your hair knotty and this is not one of those

I use this in conjunction with the conditioner and it does really make a difference! I was interested because have thicker, fuller looking hair is usually the kind of shampoo and conditioner combo that I go for. For the price of these two together it works great and smells good too!

I’ve been using this shampoo for the longest time because of the biotin in it but I recently discovered it was on a list of shampoos that are involved in that shampoo lawsuit so I decided to make the switch to a different brand. For a drugstore brand, it works, but the way it made my hair fall out made me nervous.
