Non greasy
I was concerned this product would make my hair look oily, but not the case at all. Too soon to know how effective but being that itâs non greasy I will be more likely to stick with it.

A Game Changer for Thin Hair!
I’ve been using the NUTRI-OX Densifying Tonic for a few weeks now, and I am truly impressed with the results! My hair, which has always been quite thin, is noticeably fuller and thicker. The formula feels gentle yet effective, and I appreciate that it’s both clinically and dermatologically tested. Itâs also reassuring that it’s color-safe, as I dye my hair regularly. The 30-day supply has been perfect for seeing real changes. If you’re struggling with thin hair and are looking for a solution that works, I highly recommend giving this tonic a try!

It works
This product really does work. I have used this product for years. Of course, it is not an overnight fix. You have to be dedicated and use it as often as possible. The only reason I didn’t give it five stars is because of the fragrance. While light and not too offensive, an unscented version would be great!

My go to for thicker hair.
I have used this product for a while. It’s very easy to use with your morning routine. This product makes your hair grow thicker.

caused hair to become “fuzzy” looking
I used as directed and after about a month i noticed I had fine crimped looking whispy hairs all over my head.. It was no longer smooth and bouncy.. I stopped using and after only a couple of days my hair was much smoother and about a week before it was back to being healthy looking.. I have nice healthy hair is thinning with age ect so I thought I would give this a try… for me… not a good product

Unisex
Not just for men! I’m a woman who uses this along with all my other hair products for thicker longer hair. Smells great, not sure of the results yet, but most likely will purchase again.

Horrible product
After spraying my hair became dry with edges like straw; naturally curly it gets straight and lost its shine.Don’t buy, don’t waste your money.
