Using a scalp oil for hair growth is one my favorite steps to getting longer hair. Seriously, scalp oils are a game-changer if you have thinning hair or are just looking to increase the density density of your hair.

Scalp oils that are formulated specifically for hair growth contain scalp-healthy ingredients that can improve the condition of your hair and scalp in addition to stimulating hair growth. Finding one that calls out hair growth as a benefit is important as some scalp oils aim to balance oil production or tackle flakiness and irritation instead. Below are some of the best scalp oils for hair growth with proven track results of success.

How Scalp Oils Promote Hair Growth

Scalp oils and serums work by stimulating the scalp and follicles to grow hair where it has stopped growing or to grow hair thicker, leading to a more dense appearance. Scalp serums that aim to help regrow hair contain ingredients like turmeric, rosemary, and caffeine which are often paired with peptide blends, new innovative ingredients with early promise for hair growth, or ingredients which have long been studied for hair growth effects.

Whichever scalp oil you use, it’s important to use it consistently in order to see results. Using it daily and take care not to wash it out afterwards as you want the product to really sink into your scalp.
