Can I have a perm the day after washing my head?

You can have a perm the next day after washing, but the hairdresser won't advise you to have a perm at this time. Because at this time, perming will damage the hair and make it brittle. If you want a perm, you'd better wash your hair for three days. This period is more suitable, there will be oil on the hair, which can protect the hair well and will not damage the hair when perming. So if you want to protect your hair well, you should choose a reasonable perm time.
