[This review was collected as part of a promotion.] I have really liked this conditioner. It has left my hair soft and smooth, and improved the frizziness/flyaways and roughness. I haven't used it long enough to comment on the strengthening/thickening aspect. I'll have to use it a bit longer to see if it's made a difference. It does have a strong scent, so if strong scents aren't your thing you may not like this. It does fade from your hair a bit after rinsing and drying, but will linger in the tub/shower/bathroom. It smells like a musk-based scent to me (the product info on Ulta states the scent is bergamot, jasmine, and vanilla). It's not my favorite scent, buts its okay. I like that it is sulfate-free, paraben-free, and dye-free. This bottle size retails for $5.97 on Amazon and $6.97 at WalMart which I feel is an acceptable price. *I received this product complimentary from Influenster for my honest review.*

[This review was collected as part of a promotion.] The scent smells absolutely amazing! However I had to use a lot of conditioner because I have very long hair. My hair is thin and wavy. So maybe it's not the best for hair type but it's great conditioner for other hair types.

The OGX Biotin & Collagen Shampoo and Conditioner formula aims to strengthen hair strands and promote volume. The shampoo creates a rich lather that cleanses the scalp without stripping natural oils, while the conditioner provides a lightweight yet nourishing finish that helps detangle and smooth hair. I have been using these products since past 2 years.

[This review was collected as part of a promotion.] I recently tried the biotin and collagen conditioner for the first time and I was really surprised! This smells really good, and the I love the bottles. Immediately my hair felt softer. The price is great for amount you get and it works excellent. I started with the shampoo followed by the conditioner and let my hair air dry, my hair was soft and shiny & I noticed some extra volume and my curls looked more defined and alive.

[This review was collected as part of a promotion.] I finished this whole bottle before reviewing and can say I will definitely repurchase. This is worth the money and lasts much longer than I would have expected it to based on the size of the bottle. This conditioner leaves my hair feeling so soft and healthy which is what i look for. The scent of the product smells great leaving a luxurious smell and feeling to my hair. I love the size of these bottles and lasted me so much longer. Within the past month, my hair has felt super soft and more voluminous. With some other hair products I feel that my hair gets oily quicker and with this product I feel total opposite with healthier hair. Will definitely purchase.

[This review was collected as part of a promotion.] I am just starting using this conditioner and am liking it so far! The conditioner smells really nice in the shower but doesn't stick around for too long. I like that my hair feels smooth and tangle free after using this. I'm getting some volume at the roots which is good when using this combo of shampoo and conditioner.
