What Is Henna?

Henna is a small tree or a branched glabrous shrub with axillary panicles of white flowers and small opposite leaves. It is generally cultivated for its leaves, but its seeds, flowers, roots, and stems are also used in traditional medicine. (7)

Henna grows in dry, subtropical regions where the temperature at night doesn’t go below 11°C. Henna can survive at a 45°C daytime temperature and 50 mm of rain annually. (7)

As a major commercial crop, henna is cultivated in the hot and dry climates of the northwestern states of India. In Punjab, Madhya Pradesh, and Gujarat, henna is farmed to be sold as hair dye. In Rajasthan, henna is produced for body art. (7)

Benefits of Henna Oil for the Hair

Henna oil is an ancient hair care remedy that protects and moisturizes hair and fights dandruff and lice. Its benefits are as follows.

1. It regulates oil secretion

The scalp produces oil naturally in the sebaceous glands, but environmental factors affect natural sebum production, (8) leading to hair loss and constant itching.

Researchers claim that henna powder reduces excessive oil in the scalp and conditions it well. (1) It also manages and treats oily hair and scalp. (9) Thus, it helps in oil regulation.

2. It fights dandruff, head lice, and itchy scalp

Henna’s antibacterial and antifungal properties (10) fight head lice, (2) dandruff, (2) and itching, (2) providing cooling and soothing effects. Moreover, according to a 2022 study, henna prevents itchiness on the scalp. (2)

Henna also inhibits the growth of Malassezia species (dandruff-causing organisms).

3. It strengthens and repairs hair

According to experts, henna forms a protective layer on the hair shaft from damage. (11) It repairs damage caused to the hair and scalp, thus strengthening the hair. (9)

Also, a 2018 research reported that henna oil strengthens the hair (4) and prevents the cuticles from splitting. (7)

4. It promotes hair growth and reduces hair fall

A 2022 research reported that henna stimulates hair growth, (2) and a 2018 research noted that henna balances the scalp’s pH levels (1) and controls premature aging.

Thus, henna oil promotes hair growth and reduces hair fall.

5. It makes hair soft and manageable

A 2020 research reported that henna conditions the hair, giving it bounce and improving its manageability. Additionally, henna oil adds shine, luster, and volume to the hair and boosts hair growth.  (5)
