René Furterer shampoo I'm trying out out of curiosity

This is the René Furterer shampoo I am trying out out of curiosity because the sunlight is strong and my scalp and hair are weak.

It seems mild and not very irritating.

My scalp is sensitive, so I hope this helps.

The cleaning power is decent, and it lathers well.

I heard people say the scent isn't very good, but I think it's fine, like a grassy scent.

They say it is better to use a small amount to lather up first and then wash thoroughly, rather than using a lot of shampoo at once.
