This is a brewer's yeast hair pack.

My hair had become very dry and brittle, so while looking for a hair mask, I found the Beer Yeast Hair Mask from Chin Skin.

I heard that biotin, found in brewer's yeast, is an essential nutrient for hair health.

I apply it evenly to wet hair after shampooing, and rinse it off with lukewarm water after showering.

When my hair was really rough, I used to do it up to 2-3 times a week.

The dry, frizzy feeling has mostly disappeared, and my hair has gained shine.

I'm seeing results, so I'm using it consistently.
