René Furterer shampoo good for thin hair

It's also known as frog egg shampoo, right?

It is a René Furterer hair loss management shampoo, and I have been using it for several years because it is so good.

I can't understand why my hair gets frizzy even though I've bought it so much ㅠㅠ but René Furterer products are good for thin, falling-out hair.

I use a lot, so I use the large size. I am satisfied because it doesn't run out easily even when I use it liberally.

I try to rub thoroughly to make good use of those green granules when washing, but they keep slipping off the sprayed water, so I end up rubbing hard as soon as they touch my hair haha.
