Birchbox Breakdown

There comes a time in every man’s life when his once-glorious mane begins to look, well, kind of sparse. No matter—it’s about making the most of what you’ve got and using the right kind of products. On the latter front, we’re fans of this professional-grade treatment, which thickens hair and keeps it healthier over time. The high-tech formula is designed to strengthen existing hair follicles and protect them against the enzymes that cause hair loss.

How to Use

After shampooing, spritz onto towel dried hair. Work the product into your scalp. Do not rinse.

Love this stuff. Works as it says, and smells great too. Wonderful, now I have to spend $75 on spray and shampoo.

Really really good

Loved this stuff. I don't usually shell out more than $10 for a bottle of shampoo, but that's about to change.
