Best Oils for Hair Growth

Since ancient times, the following hair oils have been used in India to increase hair growth, reduce scalp itchiness, and get healthy hair.

1. Castor Oil for Hair

An animal study suggests that external application of castor oil on the scalp for 3-4 months stimulates hair follicles, resulting in hair regeneration. Also, the hair on the area in which castor oil is applied becomes stronger. Castor oil also contains fatty acids like oleic acid, linoleic acid and glycerol, which increase the absorption of oil and keep it nourished and healthy. This can indirectly promote hair growth.

2. Rosemary Oil for Hair

Rosemary is one of the most popular hair oils for hair growth. According to research, rosemary is a medicinal plant, and its oil is more effective in treating alopecia (medical name for extreme hair loss) than minoxidil.

However, there is a lack of scientific research material to confirm the efficacy of aloe vera for hair growth. An old study discussed the potential hair benefits of aloe vera. Several participants were asked to regularly massage their scalp with a lotion that contained aloe vera. In a few weeks, the participants experienced reduced hair fall and increased hair strength. But, since other ingredients were used along with aloe vera, the effectiveness of aloe vera for hair growth could not be confirmed. Aloe vera oil for hair is extracted from aloe vera leaves and has soothing and wound healing properties that help treat scalp conditions and improve blood circulation to the scalp, thus boosting hair growth.

8. Kalonji Hair Oil

Almond hair oil is better for people who have oily skin because it is less comedogenic than coconut oil which means it is less likely to clog pores, whereas coconut oil can clog pores, causing more acne.

Almond oil has more fatty acid content that provides deep nourishment in comparison to coconut oil. However, if you have dull, damaged and brittle hair due to protein deficiency, coconut oil will be better than almond oil because it prevents protein loss.

Is Castor Oil Good for Hair Growth?

Castor oil contains several nutrients like omega-3 fatty acids, vitamin E, and antioxidant compounds like phenolic acid, flavonoids and ricinoleic acid that help reduce scalp inflammation and increase blood circulation in the scalp. This indirectly promotes hair growth. However, applying only castor oil to your scalp is not directly beneficial for hair growth. In fact, castor oil has a heavy consistency and does not get entirely removed from the scalp easily. This can cause bacterial growth on the scalp, which might lead to more hair loss. Therefore, it is best to use essential oils like castor oil, peppermint or argan oil with other light carrier oils like coconut or almond oils.

Risks and Potential Complications

There are several benefits of oiling hair, like it improves blood circulation in the scalp, making it healthy. Oils also nourish hair, help reduce frizz, and protect hair from heat damage. However, there can also be some risks and potential complications of using hair oil.

  • Increases dandruff- Dandruff is dry flakes on the scalp that get formed when the scalp starts producing extra sebum or oil. Therefore, applying hair oil in case of dandruff will increase the sebum on the scalp and lead to more dandruff.
  • Might cause acne on the face- You should also avoid applying hair oil if you have an oily or combination, acne-prone skin. Acne or pimples are also caused when the sebaceous or oil glands of the skin start producing excess oil. Therefore, while applying hair oil to the scalp, some of the oil can reach your face or forehead and might cause acne. Even if you have oily skin and want to apply just oil, it is better to oil your hair for 30-40 minutes before shampoo.
  • Aggravate hair fall- Oils with a thick consistency like castor oil, argan oil or coconut oil are difficult to wash properly from the scalp, which leads to the accumulation of dirt or bacteria on the scalp. It can also cause irritation and lead to hair fall. Also, vigorously massaging your hair with oil can make your roots weak and increase hair fall.

Summing Up on Oil for Hair Growth

However, massaging your scalp with hair oil is beneficial for hair growth as it improves blood circulation to the scalp, which leads to hair growth, provides nourishment to hair and makes it soft. Some essential oils like rosemary, peppermint, and onion oil have proven to be beneficial for hair growth. Certain nutrients like vitamin E, antioxidant compounds and fatty acids present in hair oils nourish the scalp, which promotes hair growth.
