Gua sha, which is an ancient Chinese medicine practice that focuses on using a smooth-edged tool to “rid” the body of inflammation to promote circulation and healing has become a trendy part of skincare in recent years. Celebrities and influencers alike have raved about the wonders of Gua sha, typically used to treat certain conditions by targeting muscles and tendons.

Beauty influencers and Chinese medicine fans are now bringing the stone to the scalp. Jade combing is said to potentially enhance circulation, hair growth, and relaxation, although there is currently insufficient scientific data to back up these claims.

Jade combing involves using a comb made of jade to stimulate and massage the scalp on the premise and belief that jade combing will increase blood flow to the area and promote hair growth.

Jade is used specifically because it is one of the most highly revered stones in Chinese and East Asian medicine. Jade has a reputation for promoting health, longevity, and beauty. Experts believe that any benefits that come from jade combing come more from the action of combing rather than the jade. All combing — whether using your fingers, a wooden comb, a plastic comb, or stone comb — can have the effect of increasing blood flow.

While research surrounding jade combing’s purported effects is still lacking, experts do not believe that they have any ill effects. In other words, there is no harm in trying it Even if there are no actual benefits, it could still have a placebo effect. Jade combing is safe when done gently and in moderation, and is unlikely to hurt you in any way. It could also be a relaxing practice.

One potential downside is the cost of high-quality jade. The prices also fluctuate widely in the absence of a market standard. You can get a comb made of lower-quality jade for less than $10 on Amazon or eBay.

It is also important to manage your expectations and not expect drastic changes.
