Some of the herbs that help stimulate hair health and growth include aloe vera, horsetail, saw palmetto and evening primrose, reports Clutch magazine. Many of these herbs work by stimulating the scalp, which contains the hair follicles. No herb can completely prevent baldness, however.
Aloe vera stimulates circulation in the scalp, which promotes hair growth. It also helps hair retain its moisture and thickness and is helpful in preventing alopecia. Aloe vera should be applied directly to the scalp.
Horsetail contains aluminum, manganese, potassium and silicic acid, all of which help prevent hair loss. Rinsing the hair with a solution made of horsetail leaves boiled in water is the best way to apply this herb. Avoid excessive use of horsetail, which can dry the hair.
Saw palmetto contains phytosterols, which may help stimulate hair growth. Some people consider the herb a natural cure for baldness, though clinical support for this belief is limited as of 2014.
Evening primrose helps to increase blood circulation. It also contains high amounts of gamma-linolenic acid, an essential fatty acid which stimulates hair growth. Evening primrose is available in capsule and oil form.
The anti-inflammatory properties of green tea are well known; they combine with green tea's stress-reducing properties to help promote hair health. In addition, green tea contains polyphenol catechins known to inhibit the enzyme which helps cause male pattern baldness.
