Birchbox Breakdown

Few phrases strike terror in the hearts of men quite like “this one: "male-pattern baldness."” Quell your fears with this award-winning shampoo, which fights hair loss from the root. Menthyl lactate and peppermint oil help block DHT formation (the main culprit of balding), while dissolving sebum and other scalp buildup. Meanwhile, a coconut-derived conditioner and Vitamin B5 leave your stands looking mighty-fine.

How to Use

Apply to wet hair and massage mixture into a rich lather. Rinse well and repeat. The formula is highly concentrated, so a little goes a long way.

Hey Billy

I knew a guy named Billy once. Not William, just straight up Billy. His parents smoked a lot of pot.
This shampoo is cool but also reminded me of Billy, who is dead but was a cool guy. 4 stars for muthafuckin Billy.

Very disappointed. Very runny and really not very good for thinning hair. Many other products out there much much better than this. Returning it.

My barber loves this stuff.... so do I!

Though this product doesn't proclaim to grow hair, it does give a guy a feeling that he's not thinning anymore. My barber will have business with me for a long time. Gives your hair a thickness and lushness that the gal's will notice. Honestly!

So fresh so clean!

Hands down, this is the best shampoo and conditioner I've used yet. It almost smells like it has a hint of sweat pipe tobacco. A real old school scent. I will definitely make this a regular purchase.
