Beauty Hacks You Shouldn't Try at Home

The Hack: Using a combo of lemons and salt to help clear dandruff.

Safety First: The skin on your head is an extension of the skin on your face and should be treated with the same level of care. "Lemons are antiseptic and antifungal so they may help combat the fungus that can cause dandruff called malassezia furfur," says Henry. However, she also notes that the combination of lemon and salt is excessively drying. Not only can the acidity of the lemon irritate the scalp, but both the lemon and salt can suck all the moisture from the scalp and the strands growing from it — and dryness can lead to breakage. "I would not try this without using a rich deep conditioner afterwards," says Henry.
