While this list offers you a good number of options of oils for hair growth and thickness, it is important to understand the benefits of each type to determine the best oil for your hair type. Here’s a guide to help you pick the right one.

How To Choose The Right Oil For Hair Thickness?

  •  Coconut oil

Coconut oil for hair thickening treatment is ideal for dry and frizzy hair specifically, and any hair type in general. It is proven to minimize loss of proteins from the hair shaft, which helps keep frizz away. It contains fatty acids and lauric acid that penetrate deep into the follicles to provide moisturization and protect the hair from damage. It has antibacterial, antifungal, heat protecting properties and also prevents damage from UV radiation.

  • Argan oil

If you have buildup and dandruff-related hair issues, we recommend argan oil. Rich in vitamins A, C, E, linolenic acid, tocopherols, polyphenols, and antioxidants, argan oil helps reduce inflammation and an itchy scalp to treat dandruff and psoriasis. It is a great antioxidant that nourishes and conditions the hair and reduces split ends and hair breakage. It is used in hair sprays as well because it works well for controlling frizz.

  • Castor oil

Castor oil can help reduce hair fall and hair thinning and aids in hair growth. It is rich in mono-saturated acids that can help prevent dryness by locking moisture in your hair. When you apply it to your scalp, the ricinoleic acid present in castor oil not only stimulates blood circulation but also helps provide more oxygen and nutrients to your hair, further stimulating hair growth.

  • Tea tree oil

Dandruff can prevent your hair from growing as it does not allow the hair to get enough proteins. If dandruff is your major concern, you can try tea tree oil. It has anti-inflammatory, antibacterial, and antifungal properties, which help treat dandruff, infections, and seborrheic dermatitis.

When looking for the best oils for hair growth and thickness, it is best to assess your hair type, scalp, identify any hair and scalp conditions or infections, and weather conditions in your area before deciding which oil to buy. We recommend you do a patch test by applying the oil behind your ear before you apply it to your scalp. Just like our body needs proper nourishment to grow and stay healthy, our hair is at its best when the scalp gets the nutrients it needs to boost hair growth. Pick one of the best hair oils, and you’ll see how impressive the transformation of your hair from dull, thin, and lifeless to thick, shiny, and full of life can be.
