Firming shampoo I bought with my own money

Since it's summer and my hair feels heavy and limp, I found this shampoo to give it some elasticity: 'Elastine Collagen Volume Elasticity Care 10X Shampoo'.

It smells nice, so it makes me feel good after using it!

I heard that this product gives elasticity to hair because it contains plant-based protein. Also, since it includes protein extracted from soybeans, I think it would be good for the scalp too.

This is a shampoo that will help weak hair during the summer!
