I recommend this shampoo for thin hair or sensitive scalps.

It's a Rausch Willow Bark product, and I heard it's a shampoo that's really popular among people with hair loss?!

The volume is smaller compared to regular shampoo and the price is quite high, but I also used this last year for the aftereffects of COVID-19

It used to feel a bit sparse at the crown, but a lot of baby hairs have grown in, and since my hair is on the thinner side, I'm not sure if it has definitely gotten thicker or what.

It has gained some strength. However, since the texture is more watery and runny rather than viscous, it doesn't lather well. If you just pour it into your hand, you end up using a lot... so I recommend buying a bubble maker from Daiso, filling it with a little water, squeezing in the shampoo, and making lather to use.

It's cost-effective, I like that the shampoo doesn't touch my scalp directly, and it lathers better than rubbing it in my hands, so I use it this way.

I recommend this to those with weak hair! I buy it at Olive Young when it's on sale.
