Since ancient times, onion has not only been used in India but across the globe for reducing hair loss and promoting hair growth. Recent research has shown a 74% efficacy of onion juice in promoting hair regrowth in adult males and females affected with alopecia areata or patchy baldness. Clinical studies continue to demonstrate the role of onion ointment/extract and onion juice in improving skin inflammation and treating damaged hair follicles. Let us know more about the role of onion in maintaining healthy hair.

According to Dr Ravichandran G, a dermatologist associated with Apollo 24|7, “in men, pattern hair loss termed as androgenic alopecia (balding) is the major reason for hair loss. If recognised early, this can be reversed with the help of effective treatment options. While in women, diffuse alopecia secondary to thyroid disorders, anaemia, and telogen effluvium are responsible for severe hair loss. All these conditions can be treated effectively by your dermatologist.”

The power of onion to control hair loss

The anti-inflammatory and antioxidant properties of onion help treat several long-term skin infections and other debilitating diseases such as diabetes, obesity and hypertension. However, the recent evidence on hair loss prevention and hair regrowth benefits of onions has gained considerable attention in the scientific community. The findings from a study confirmed hair regrowth in 87% of patients who consumed onion juice each day for 8 weeks. Furthermore, scientists continue to gather more evidence to possibly include onion ointment, onion juice or onion oil in conventional hair fall regimens for treating hair loss.

Unique Properties of Onion

Onion juice is known for its nourishing power, hair growth-stimulation potential and antibacterial properties. Onion extracts containing quercetin and cysteine are known to reduce the signs of ageing and itching, and inflammation of the skin. Onion contains several skin-benefiting nutrients like potassium, magnesium, calcium, vitamin B6 and vitamin C. The sulphur in the onion not only nurtures but also adds natural beauty to nails, skin and hair. These nutrients improve blood circulation, and minimise dandruff, hair thinning and hair dryness that eventually foster hair regrowth.

How Does Onion Extract Reduce Hair Loss?

The onion extract traverses the outer and inner roots of the hair follicles and fights the infectious or disease-causing antigens that attempt to contaminate the surface of the scalp. The detoxifying properties of onion extract eliminate these antigens, clear the scalp capillaries and increase their blood supply. The routine application of onion protects hair follicles and minimises hair fall by increasing the accumulation of skin cells, like keratinocytes and melanocytes, in hair roots.

Though no side effects of onion juice or extract have been reported, some people may experience heartburn or skin irritation after using it. Moreover, individuals with a known allergy to onion should avoid its oral or topical use and consult their physician for alternative hair loss remedies.  

The hair regeneration and skin-nurturing properties of onion make it the preferred remedy for hair loss control and regrowth in adults with temporary or permanent hair loss. However, you must consult your physician to know more about the benefits and use of onion for your hair condition.
