I recommend Tsubaki shampoo.

This is Tsubaki Premium Repair Shampoo.

My hair was very damaged, so I was looking for a nourishing shampoo and tried this; my hair became soft after just one use.

It has a lovely floral scent that makes hair soft even when used alone without rinse or treatment.

If you have severely damaged hair that gets tangled and is difficult to wash, please give this a try. I recommend it.
