Leave it for a few hours or until it dries up then wash it off. It’s hard to move around while you have them on your heels, so it’s better to apply it at night. You may repeat every week or twice a week (if that’s not too hard for you). It gradually heals the cracks and your heels become soft again.

Disadvantage of henna for hair

Henna side effects

Red henna is relatively safe for most people. However, there are a few reports of contact allergic reactions. It may cause inflammation, redness, itching or burning sensation when applied on the scalp or on body parts for some people. In some countries such as India that it has been used extensively, many people have been exposed to henna, so the sensitivity reaction to henna must be negligible.

If that is the first time you are using it always apply it on a small part of your body like the inside of your elbow. Wait for 48 hours and see if that area is red, itchy or burning, you may skip applying henna on your scalp. If you decide to give it a try after a while, repeat the test.
