This system has a very good smell. However, I didn't notice any added thickness to my hair. My hair was very soft and shiny after use, just no change otherwise. I would use again, just not if I'm looking to thicken my hair.

I've been buying this OGX, but I don't notice any difference in the thickness of my hair or the fullness. Overall it's a fine shampoo and conditioner, but I'm not in love with it.

I love having this in an overnight bag for a weekend trip! It smells great and definitely helps retain moisture and shine. My hair is slightly frizzy which can be a problem but I find that this is a great go to, especially if you have thicker hair.

I absolutely love this shampoo. It smells wonderful and truly does help thicken hair. It doesn't weigh your hair down, and gives you a lot of body. A little goes a long way!

I love this shampoo. It's so hard to find a shampoo without the sodium sulfate for a decent price, so this is a great find! It lathers nice, smells amazing, and gives my fine and thin hair great volume. Will be repurchasing

I recently started using this shampoo along with the conditioner. The smell is amazing! Also, my hair feels a lot smoother and stronger. I would recommend this to anyone with damaged hair.

I alternate between using this and the keratin shampoo and condition. I love both scents and both have helped keep my hair healthy and shiny. It is extremely affordable. It doesn't leave my hair feeling dried out or greasy. Will always repurchase.

I absolutely loved the Biotin Shampoo. It has a fantastic scent and the scent will last all day. It lathers extremely well. It's just hard to find here. I am very satisfied with this product and I will buy again!

This made my damaged dyed hair feel much healthier and the smell is great too! Not pricey either so I highly recommend if you're trying to fix your damaged hair

This is my new favorite shampoo. I used a different scent of this brand and love this one so much. It smells sweet, but natural. It doesn't smell too much like chemicals or too unnatural. It leaves my hair feeling great as well.
