Ginger Extract and Hair: What are the Benefits?

The ginger, more specifically ginger essential oil, is first and foremost an ingredient that stands out for its antibacterial power. Indeed, its oil is rich in limonene and α-pinene, terpenes that have bacteriostatic effects useful for keeping the bacterial populations of the scalp under control. Therefore, it may be beneficial to regularly apply ginger oil to the scalp through massage to take advantage of its sanitizing effect.

Note : Ginger essential oil should never be applied undiluted to the scalp. It is strongly recommended to dilute it to 1 or 2% in a carrier oil.

Ginger can also be used to combat the tingling or tightness sometimes felt on the scalp. Indeed, this plant is an effective natural anti-inflammatory for easing mild irritations. This property comes from its biochemical composition, particularly from the geranial it contains. Studies have shown that this isomer of citral reduces the activity of NLRP3, an inflammasome complex that triggers a pathway of inflammatory signaling and the synthesis of pro-inflammatory cytokines (interleukin-1β and interleukin-4).

Ginger can also be utilized through a warm water compress or as a massage oil on an irritated scalp. After a few minutes, redness and itching subside, as well as sensitivity to pain.

The gingerol and shogaol found in the ginger are two active ingredients with antioxidant properties, allowing them to combat oxidative stress. Studies have indeed shown that these molecules stimulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GPx), antioxidant enzymes.

In doing so, ginger protects the hair from free radicals, which are generated following exposure to UV radiation or pollution. It's important to remember that these reactive species can weaken the hair follicle and promote hair loss and the appearance of split ends.

We often hear that ginger is an interesting ingredient for stimulating hair growth. However, this is a misconception. Furthermore, scientific studies conducted in vivo and in vitro on this subject show, on the contrary, that ginger has a suppressive effect on hair growth. Gingerol, one of the active principles of ginger, has pro-apoptotic effects on human dermal papilla cells and tends to reduce the rate of hair regrowth, the number of hair follicles, and their length via various mechanisms.

Advice : If you desire longer and stronger hair, ingredients other than ginger can assist you. We recommend, for instance, caffeine, nettle extract, or even red ginseng.
