It's the second S Solution bought! 

My dad used it and it worked great, so I bought it for my boyfriend. 

It is already my second purchase. 

Dad had very thin hair, but as he has used it steadily, he now hears a lot about his hair getting thicker. 

Oh, and the essence seems to be less irritating than other hair loss products. 

When my boyfriend was prescribed medicine while going to a hair loss clinic,

it turned red with applying the incorrect amount on the forehead side. 

But this product doesn't seem to have anything like that. 

Seborrheic scalp irritation is also severe, 

so I hope that it will be effective this time with Sebo shampoo.
