First & foremost- this shampoo is THEE BEST smelling shampoo i have ever smelled! I cannot stress that enough. Smells amazing! Now, when it comes to moisturizing and taming frizz? It’s a no go. I have very wavy, frizzy hair and after using this it is the exact same as it was before- wavy, frizzy, and now dry. I just wish it worked better AND could keep the scent! (Seriously- please make this a perfume lol)!

Smells great and I actually feel like it’s repairing my hair. My hair doesn’t have as many flyaways which I love and it makes it tougher if that makes any sense. I recently went black to transitioning to blonde so my hair relies on great products like this.

I absolutely recommend this shampoo, it really helps with breakage and especially with thinner hair. I usally use the shea moisturizer shampoo but the price was ughhh but then i found OGX. I really do see a difference in my hair. It looks fuller and feels very soft.

My hair gets quite dry and frizzy after washing and drying and this shampoo (as well as the matching conditioner) make a huge difference for me. It really helps to make my hair lay down and not puff up. The smell is wonderful. Kind of sweet but not too perfume-y. (It compliments my vanilla perfume)

I recently purchased Thick & Full Biotin & Collagen Shampoo after reading the reviews. I have slightly curly hair that can be dry due to our hard water issues. I like to wash my hair daily but it becomes too hard to the touch. This Biotin works well with my hair and leaves it feeling soft and manageable. I personally have noticed my hair looks thicker and I believe It's due to the Collagen in the ingredients. I will continue to purchase and use this shampoo.[product:ogx-thick-&-full-biotin-&-collagen-shampoo-13-fl-oz]

I really like this shampoo! It makes my hair feel smooth and shiny for few days. I read some reviews that when you stop using it your hair begins to fall out. It’s a concern for me as mine is very thin already. I alternate between different brands as my hair gets immune to one brand after using it for 4 months

[This review was collected as part of a promotion.] I was given this product complimentary for my honest review. Honestly I can’t really tell much of a difference from the amount of time I’ve been using it. Maybe a little more volume. It smells absolutely amazing though. It has a nice consistency and suds up well. I’m going to continue to use it to see if I get more results.

This shampoo was making my hair fall out! I originally bought the conditioner version of this and LOVED it - it smells so nice and makes my hair feel great, so I thought I’d try the shampoo. It smells horrible and causes way more shedding, even after using it for a few weeks. My hair looks lackluster too. Do not use!!

I am loving this shampoo! I have been suffering from hair loss/thinning . And lack of volume. This shampoo has brought my hair back to life! The lather is just right. It has a delightful smell to it. As far as cost goes it is not to expensive and you can definitely find it really easy at most stores.

I have had problems with my hair thinning recently, I did have really think wavy/curly hair and wanted my hair to get it back that. Read a few reviews on this particular product and looked on YouTube etc.. before I eventually purchased it. Was a little apprehensive at first as I’m not one for a ‘beauty products’ or partically expensive hair products. I’m a very mixed bag on this product. The good points:- shampoo & conditioner have such a nice sweet smell, makes my hair soft & relatively shiny. Does is make my hair thicker? No. It just makes it go greasy really quickly. I literally only used to wash my hair twice a week & now it’s every other day. I probably wouldn’t buy this product again although it is not a bad shampoo at all.
