Why There’s So Much Buzz About Biotin Hair Oil
If you’ve spent time searching for ways to help thinning hair, dryness of the scalp, or lackluster hair, you’ve probably seen biotin hair oil. So is biotin hair oil just a beauty fad, or is this the next big thing based on real science? We interviewed dermatologists, reviewed clinical studies, and researched consumer reviews to find out. Here are the results. Spoilers; the results may surprise you.
What is Biotin Hair Oil?
Biotin, a.k.a. vitamin B7, is a water-soluble vitamin involved in keratin production, the primary protein of your hair, skin, and nails. Biotin hair oils generally combine biotin with carrier oils, like coconut, argan, or castor oil to better absorb into the scalp while also nourishing your hair.
The Benefits of Biotin Hair Oil (What Dermatologists Say)

1. Supports Thicker, Stronger Hair
“Biotin helps keratin structure, which makes strands more robust and less prone to breakage,” says Dr. Melissa Burnstein, a board-certified dermatologist in Los Angeles.
Stat to Note: A 2017 study in the Journal of Clinical and Aesthetic Dermatology found women with thinning hair grew significantly more hair, and the thinning of their hair became less apparent, after taking biotin supplements.
2. Improves Scalp Health
A healthy scalp taps into healthy hair. Biotin oils contain anti-inflammatory oils such as tea tree or jojoba oils that help reduce dandruff and also help to unblock clogged hair follicles.
3. Aids in preventing hair breakage and split ends
Biotin oils have an abundance of vitamin-rich base oils within the serum structure to create a water-resistant seal to the hair cuticle protecting it from ongoing friction and damage/blunt ends from combing and styling.
4. Better shine and texture
Many users have reported they were able to achieve shinier/smoother hair with regular use of biotin oils. The oils include fatty acids such as argan oil and almond oil that improve hair texture when combined with biotin oils.
How to Use Biotin Oil for Hair: A Five-Step Process
Step 1: Warm the Oil
Duchess will require 2-3 tablespoons of biotin oils to do an effective hair treatment, so that is what you need to measure into a small bowl. Just warm the bowl in the microwave slightly (take care not to overheat the oil). Warming the oil helps to improve absorption to the scalp.
Step 2: Massage into scalp
With your fingers, massage the oil into the scalp with a circular motion for approximately 5-10 minutes. This should serve to stimulate blood circulation to the scalp and hair follicles. Use your fingers to distribute, not the palm of your hand.
Step 3 – Distribute through hair
Use a wide tooth comb to distribute the oil evenly through the hair from root to tip.
Step 4: Leave it in
Leave it in for a minimum of 30-minutes, if you want to really nourish your hair leave it in overnight.
Step 5: Wash and rinse
Make sure to wash out the conditioning oil thoroughly with shampoo. Use conditioner again after washing out with shampoo. Do this process 2-3 times per week.
