Losing hair can feel frustrating and even a little scary, but you’re not alone — and there are ways to fight back. While shedding some strands is natural, weak roots and thinning hair can lead to noticeable volume loss over time. The good news? The right hair oils can deeply nourish your scalp and strands, helping to strengthen from the roots up. With consistent use, certain oils are known to promote massive volume and thicker, healthier-looking hair.
Read on for tips, suggestions and insight from Ghanima Abdullah, hair expert and cosmetologist at The Right Hairstyles, Dr. Yoram Harth, MD, board-certified dermatologist and Medical Director of MDhair and Dr. Mitchel P. Goldman, MD, Ph.D., board-certified dermatologist and cosmetic dermatology expert.

1. Rosemary Oil
According to Abdullah, rosemary oil "works against the hair loss hormone DHT," and "the hairline and crown are common areas of thinning for women with hair loss that's related to age." She advises "adding a few drops of rosemary oil to a 4 ounce bottle of lotion." Lotion works just as well (if not better) than oil for some women with thicker textures because it "absorbs quicker into the skin," she explains.
Abdullah recommends "using this solution twice daily." She stresses not "expecting to see results overnight," as it often takes "at least six months" to see hair regrowth at the crown. "If you're not sure what type of hair loss you have, use more than one essential oil [on its own or in] your lotion," she recommends.
Harth adds that "a healthy scalp environment can lead to improved hair growth and a reduction in hair loss." The best scalp oils or scalp treatment serums would "include DHT blockers that help reduce the effects of DHT on the hair follicles," he notes. (Keep an eye out for this on your product's label!)
2. Peppermint Oil
Another oil that often leads to stronger, thicker and healthier strands is peppermint oil, Abdullah shares. Using this along with rosemary oil can "stimulate the hair follicles, and hydrolyzed protein and collagen can help fortify the hair shaft against damage and breakage," she says.
Regarding haircare products as a beginner, Harth says that "particularly those designed as scalp treatment serums," can be "beneficial for thin, fine hair." These oils, like many rosemary and peppermint-infused options, are "formulated to promote scalp health, nourish the hair follicles, and stimulate blood circulation in the scalp."
3. Pumpkin Seed Oil
Abdullah also recommends trying a "pumpkin seed oil" for your hair and scalp, as it has been "scientifically proven to grow more hair and aid those who have thinning hair."
She continues: "The best oil for thickening hair is pumpkin seed oil. It puts more hair follicles into the hair growth phase, which means you can see thicker hair near the roots in as little as three weeks."
4. Castor Oil
“Castor oil is a popular natural remedy for hair growth,” Goldman explains. “It contains ricinoleic acid, which has anti-inflammatory and antimicrobial properties that can help to improve scalp health and promote hair growth. Additionally, castor oil is high in omega-9 fatty acids essential for healthy hair and skin.” Goldman emphasizes the importance of conducting thorough research before selecting a bottle of castor oil.
“When it comes to using castor oil, there are a few things to keep in mind. Firstly, it's important to choose a high-quality castor oil that is free of additives or impurities,” he says. “Secondly, use it sparingly — a little bit goes a long way. You can apply a small amount of castor oil to your scalp and massage it, leaving it on for 30 minutes to several hours before washing it.”
5. Lavender Oil
According to experts, lavender essential oil possesses the power to improve scalp health, stimulate hair growth, and even reverse alopecia symptoms. It accomplishes this by soothing the scalp, healing hair, and stimulating follicles.
Additionally, the antifungal properties of lavender oil play a crucial role in maintaining scalp health and promoting overall hair health. Hence, including lavender essential oil in your hair care regimen is highly recommended.
6. Jojoba Oil
Jojoba Oil shines brightly in the arena of hair growth. Abundant in hair-nourishing vitamins and minerals such as vitamin C, vitamin B, vitamin E, copper, and zinc, it provides essential nutrients that moisturize the scalp, condition the hair, and ward off dryness, dandruff, and hair breakage, according to hair experts. Though coconut oil can serve as a substitute, Jojoba or Argan oil generally function better as carriers.
The Bottom Line
There are "two main types of hair oils," Harth explains. Whether you're noticing hair loss or thinning or just want to prevent this from happening, Harth says that using two different kind of oils in your routine is best. The first is "applied to the scalp skin and intended to help with scalp health and hair regrowth," he notes. This is called a scalp treatment serum.
"The second type of hair oil is applied to the hair strands and is intended to help strengthen the strands and reduce breakage and split ends," he adds. Both of these types can contain rosemary and peppermint oil as ingredients. Ultimately, Harth suggests that regardless of your choice between oil, lotion, or a combination of the two, it's widely known that nourishing your scalp and dedicating extra attention to hair care can yield remarkable benefits, including combating hair loss and thinning.
