Whether the issue was a bad haircut, a case of COVID, or a struggle with thinning hair, just about all of us have struggled at some point to grow out our hair. And while the key to healthy hair growth is a healthy lifestyle (i.e., hydrating, eating well, and sleeping enough), there are also a number of topical products, like hair growth shampoos and hair growth vitamins, that can enhance scalp health and stimulate hair growth alongside your regular shampoo and conditioner. One of my go-tos is hair growth oil, which can easily be applied to the scalp to give your hair growth regimen an extra boost.

But how do hair growth oils work, you ask? We spoke to Dr. Mona Gohara, a dermatologist who serves as Vice President of the Women’s Dermatologic Society at Yale University and is an active member of The American Academy of Dermatology and The American Society For Dermatologic Surgery.

"Hair growth oils are serums that help restore nutrients to your scalp and increase stimulation and hair production," Dr. Gohara explains. "Oils can thicken the cuticle, making the hair appear fuller. As the hydration is absorbed, the cuticle expands giving the appearance of growth."

How to Use a Hair Growth Oil

If you've never used a hair oil before, applying it for the first time can be a baffling experience. It's important to keep in mind that hair growth begins with a healthy scalp. For that reason, Dr. Gohara says, "Hair growth oils are massaged into the scalp to stimulate the hair at the root. Once you’ve shown your scalp lots of love, you can carry the product through to the ends."

And when it comes to frequency of use, Dr. Gohara reminds us to read the instructions for your oil of choice very carefully. "Following the instructions on your hair growth oil is imperative because some oils have you apply once a day while others are more frequent," she points out. She adds that it's perfectly alright to use multiple hair products at once, so long as you "couple your hair growth oils with a shampoo and conditioner routine to make sure your hair is getting as clean and nourished as possible." Clarifying shampoos in particular, she says, "are perfect companions for hair growth oils."

Still worried that adding an oil to your regimen will make your hair look greasy? "A lot of hair growth oils are applied before you shower," says Dr. Gohara. "However, if you have one that needs to be applied in the morning, you can always rock a sleek bun or pony!"
