It's easy to drive. It only takes one month after perm. If your hair is not particularly good, I suggest the landlord not to perm it, because I just perm it with pear heads and do it in a hairdressing shop, and the price is quite expensive. I haven't got the desired effect yet. Actually, I can't blame others, but my hair is not very good. There are many ways to make pear heads. I can make them by buying a 32-yard curling iron, as shown in the figure.
