Can You Leave Henna On Your Hair For A Longer Time?

The reapplication of the henna typically depends on your hair type. In general, reapplying the mixture every 3-4 weeks ensures full and flawless coverage. But, if you are using henna to cover your grey hairs, your reapplication routine depends on your hair growth speed. If your hair grows faster, you have to apply henna more frequently to cover up your shafts.

If you undertake hair damage treatment that depletes your hair color faster, reapplying henna every 2-3 weeks could maintain the pigmentation.
