Details & care

What it is: A instant thickening formula that provides fuller, denser-looking hair while locking in style.

What it does: The formula helps rejuvenate follicles to visibly improve thickness and reduces signs of thinning hair over time.

How to use: Work in clean, small sections. Starting at the front of the head, use the nozzle tip to apply the formula directly onto the scalp and work towards the back in a straight line. Use fingertips to gently massage in and work product from roots to ends, then blow-dry and style as usual. A little goes a long way. For best results, use after every wash.

I have never been a
[This review was collected as part of a promotion.] I have never been a "product girl" until I went to Drybar to get my hair done for a wedding. I was so impressed that I ordered everything that was used on my hair. I love the way the products smell, the feel, and what they do to my hair. I get a little extra volume and longevity out of my blowouts, which I love.

It doesn't work
Not only does this product do nothing for thickness or volume but it made my hair greasy EVEN if I used the tiniest amount. My hair was also frizzy from using this and on the days I did not wash my hair, my hair looked even thinner and greasy. This is a terrible product and does nothing what is promised in you statements on your website. I can't even seem to give this product away. No one wants it.

[This review was collected as part of a promotion.] I have thinning,thin,aging hair. This product really helps my roots look thicker. I apply it, by putting a dime size on my finger and use a little at a time to spread on my scalp. Then,spread to rest of hair. When I followed the video, it was way too much. l don't have model hair as always demonstrated in Drybar aids!
