Biotin & Collagen Extra Strength Volumizing Conditioner for Thicker, Fuller Hair, 25.4 fl oz

Used this before. Very good. Does a great job.

I purchased this OGX Biotin & Collagen conditioner and my hair is much fuller! It is so easy to use and also makes my hair shinier and softer! It is t waxy like some volumizing conditioners I’ve used. I feel more confident and see less of my bald spots.

Love this conditioner. It really has been helping my hair stay healthy and even grow back from losing a lot of it after multiple surgeries. Smells good, leaves my hair soft and happy after using, and great size for the cost.

Love this shampoo and conditioner. Makes a big difference in my hair.

Veey hydrating ans silky formula, so far I've been loving this one!

What started out as a high-school science-fair exhibit showing how aspic ingredients could be repurposed as a hair-care product is now commercially available at moderate prices in huge squeezy bottles. Just goes to show what a little hard work, application, and mounds of excess collagen lying around the house can get you.

Love the smell! Hours after washing my hair you can still smell it.

I’ve been using the OGX Biotin & Collagen Extra Strength Volumizing Conditioner for a while now, and it has become a staple in my routine. Every time I use it, my hair feels noticeably fuller, softer, and more manageable. The formula is rich but not heavy, so it adds volume without weighing my hair down. The scent is clean and refreshing, and it leaves my hair feeling healthy and nourished. I also appreciate that the large 25.4 fl oz bottle lasts a long time, even with regular use. If you’re looking for a conditioner that actually delivers on thicker, fuller‑looking hair, this one is consistently reliable. I keep coming back to it because it works — simple as that. Highly recommended!
