Marc Anthony Instantly Thick Shampoo, Conditioner and Hair Cream Set - Biotin & Aloe for Thicker & Fuller Hair - Volumizing & Thickening, Product for Thin, Fine Hair - Pack of 3, 22 Ounce

I love this shampoo! My hair is extremely fine and flat. This biotin line makes it much thicker and adds volume. Switched to this two years ago and won’t use anything else!

As a thin-haired woman who has tried every kind of product, this has been the most successful for me so far. I use it two or three times a week and have done so for the past couple of years. The styling cream is good, too, even if I am not heat styling my hair. It adds some body and shine. Happy I can still get this product.

I have fine highlited hair and will only use sulphate free hair products. The shampoo and conditioner work really well, it doesn't fade my highlights and my hair is noticeably thicker but the styling cream dried my hair out. I saw other reviews that mentioned their hair getting dry and I suspect it was possibly the styling cream and not the shampoo. My hair is not normally dry so I can't speak for those who have dry hair, but for me the shampoo and conditioner works extremely well and I'll be buying more, just not this entire set.

Fantastic products! My thin hair feels shiny and thicker. I highly recommend.

I highly recommend them for people with fine hair and low density like me. I have already used it in several washes and it meets the volume it promises. If you are curly and have little density, I highly recommend it

I used almost the who bottle of the instantly thick shampoo. Not really any difference other than my hair now feels and looks more dry than what it was before I started. I would say it was easy to use, smelled good. That's all.

Last week my physical trainer told me he had never seen such a healthy head of hair any other woman my age. I smiled, cried inside, and said "Thank you Marc"

It works but I began getting acne on my head and neck and wasn’t sure it was the shampoo but On my second order and the first use of it and had to stop as my head had gotten worse with extremely painful acne, dry, itchy spots all over. I got the shampoo on my face due to a bad itch on my nose, I scratched while shampooing and I got the same painful acne under my nose and around my mouth and chin. Yes I have sensitive skin so a warning to those with the same.
