Birchbox Breakdown

Few phrases strike terror in the hearts of men quite like “male-pattern baldness.” Quell your fears with the help of this fortifying shampoo that fights hair loss from the root. The award-winning formula both thickens and volumizes hair, resulting in locks that not only last, but looks great too.

How it Works

Menthyl lactate and peppermint oil help block DHT formation on hair-producing cells while dissolving sebum and other buildup on scalp.

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.

Billy Jealousy Fuzzy Logic Hair Strengthening Shampoo

As a 20-something failing to come to terms with my impending balding, I needed this product. I was ecstatic when it arrived in my August box. The smell is alright, but I noticed my hair is softer and starting to thicken. Love it!

Probably effective, wrong guy

This product is probably really effective, but I don't have a need for it. It is supposed to be for hair strengthening to prevent baldness and I've heard good things. Just not my thing.

Great Product
Sampled

Overall it was a great product, it has a great scent and rich feeling. My only complaint is that without the conditioner it may dry your scalp out with regular use.

Did notice a difference

I definitely will say that after using this my hair did feel a little thicker. That said, it did feel dry. You definitely want to follow up with a conditioner.

Mint shampoo

This sample is great. It has a nice peppermint scent, a small size lathers up well, and it leaves my hair soft. I can't tell if it has "thickened" or "strengthened" my hair as it claims, but it contains the ingredients that blocks the buildup of DHT.
