I recommend this hair care shampoo that I bought with my own money.

I recommend J-Forest Black Shampoo haha

My hair has been in terrible condition for a long time due to frequent chemical treatments, so I didn't have high expectations, but
The softness is definitely exceptional after washing my hair!
Normally, after shampooing, my hair gets really stiff to the point where I can't even comb it with my fingers.
Even though I only used the shampoo with this product, it felt like I had finished my usual hair treatment as well.
I was worried it wouldn't lather well since it's mildly acidic, but
It lathers up so well that it makes such worries seem pointless.
It has a large capacity, so the whole family uses it. I feel reassured knowing that it will last a long time haha.
The scent is refreshing, so it goes well with summer haha.
