I didnt have high expectations since its a drugstore brand, but wanted to give it a try. Its actually pretty good! I feel like my hair is fuller when I put it up. Im definitely going to buy it again. I dont love the initial smell out of the bottle. Its pretty strong. It fades quickly though.

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!

[This review was collected as part of a promotion.] Biotin & Collagen Shampoo is an amazing shampoo , the effectiveness feels instant but more noticeable the more you use it . The scent is addictive and the packaging being the shape that the bottles are help with knowing what to look for. The price is worth the product and the shampoo leaves your hair smooth and clean.

I bought the shampoo because it is sulfate free for my dyed hair. It gives added volume to my fine hair, and it moisturizes it as well. I am happy with this product. I also am impressed by OGX's tea tree with hydration, sulfate free and argan oil hydrating, sulfate free shampoos. I wish Sam's would carry those, too. They are especially hydrating without weighing down my fine hair.

I was pleasantly surprised at how well this line worked to add substantial volume to my hair. Maybe volumizing conditioners that I’ve tried don’t do much to nourish and moisturize hair but this one does both flawlessly! And it smells absolutely amazing.

I started using this to help my hair after treatment from cancer. It has made my hair so much fuller. My scalp isn't dry either. It has a wonderful smell as well. It lathers great. I would recommend to anyone that is looking to improve the fullness of their hair.

This conditioner has really helped my frizzy hair. It has conditioned and give my hair the boost of energy that it needs. I purposely was looking for a biotin product, but since I am still breastfeeding my daughter, I have to opt for non-consumables and this is not a downer.

[This review was collected as part of a promotion.] I'm absolutely loving OGX Biotin & Collagen Shampoo! 💜 This shampoo has transformed my hair, making it feel thicker, fuller, and healthier. The powerful blend of biotin and collagen works wonders, giving my locks a noticeable boost in volume and strength. Plus, it smells amazing and leaves my hair feeling soft and manageable. Highly recommend for anyone looking to amp up their hair care routine and achieve luscious, voluminous hair!

This shampoo is like a protein shake for your hair. After a few uses, my hair felt thicker and stronger—like it hit the gym. The scent is sweet and refreshing, Don’t expect a full mane if you’re starting from a buzz cut, but if you’re looking for some extra volume and strength, this shampoo's got your back. Solid addition to the grooming routine!

I've noticed a significant difference in the strength of my hair since I started using this shampoo about 2 years ago. It has a gelatin like consistency that doesn't overly suds up when lathering. The smell is minimal and clean. Leaves my hair feeling good and not dried out.
