4 Hair-Strengthening Oils To Add To Your Daily Routine For Thicker & Shinier Locks, According To Doctors
Coping with thinning hair and shedding can be quite a daunting task, but it’s crucial to remember that hair oils and scalp serums can be valuable allies in this struggle. While most people are aware of after-styling oils and scalp serums that fight frizz and provide smoothness, they might not be aware of other oil types that can be advantageous to the scalp.
Choosing the right oil can boost hair follicle growth, nourish the roots, and promote stronger, healthier hair. With an overwhelming number of hair oils to choose from, we turned to experts in dermatology, medicine, and hair care to discover the benefits of oils like castor, rosemary, pumpkin seed, and thyme. These oils are particularly useful for women with fine hair who are looking to achieve thicker and healthier locks.
Read on for tips, suggestions and insight from Dr. Mitchel P. Goldman, MD, Ph.D., board-certified dermatologist and cosmetic dermatology expert, Dr. Dejarra K. Sims, naturopathic doctor and natural skincare expert and Ghanima Abdullah, hair expert and cosmetologist at The Right Hairstyles.
4 Essential Hair Oils & Serum Types For Women With Fine, Thin Tresses To Try
1. 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.”
2. Rosemary Oil
Sims suggests that rosemary oil can promote scalp circulation for women experiencing hair loss at the crown, potentially aiding in hair growth. "I recommend it because it can help increase blood flow to the scalp nourishing the hair follicle with nutrients," she says. Sims also describes rosemary oil to be "anti-inflammatory and it can decrease the inflammation caused by DHT attaching to the hair follicle with those with hair loss caused by increased androgens."
This, she says, "will increase hair growth in the thinning areas around the hairline and also decrease itching and inflammation often associated with androgenic alopecia." She recommends "applying 6-10 drops of rosemary oil into the affected areas of the scalp." Sims notes that this is "basically enough to cover the area but not saturate it." Then, she suggests gently massaging it in. "I also tell clients to add rosemary oil to both their shampoo and conditioner," she explains.
"I suggest using it once a day nightly for areas of thinning in addition to adding it to shampoo and conditioner and using it as often as you wash for your hair type," she continues. "I would be careful about the sources of all things you put on your scalp," she emphasizes.
"Read the ingredients list to make sure there is actually rosemary in the product and not just a fragrance that smells like rosemary." Also, Sims says to "never use rosemary essential oil directly on the scalp, as it must be in a carrier oil."
3. Pumpkin Seed Oil
Abdullah explains that pumpkin seed oil has "been scientifically proven to grow more hair and aid those who have thinning hair." She goes on to say that "pumpkin seed oil is worth it as a supplement ingredient, or even all by itself."
It can be applied topically, like any traditional oil, or through supplement form. If you are interested in supplementation for hair growth, Abdullah also says that pumpkin seed oil may be more beneficial to try than "collagen, elastin, and coconut oil" supplements. (The more you know!)
4. Thyme Oil
Although not as renowned as rosemary, castor or pumpkin seed oil, thyme essential oil is favored by doctors for its scalp-stimulating properties and potential to foster new hair growth.
Experts advise that red thyme oil enhances blood flow to the scalp, fortifies hair follicles, and nourishes both hair and scalp.
The oil’s natural thymol content serves to amplify blood circulation and improve blood flow, ultimately resulting in stronger, healthier hair.
The Bottom Line
Goldman advises against relying on any one product as a cure-all solution for your hair woes. While these three hair oils may be beneficial, they are merely a component of a comprehensive hair care routine. “Remember your diet,” Goldman adds. “Your diet should be rich in vitamins and minerals. While using these oils, you should always be mindful of what you eat.”
When it comes to issues related to hair loss or other hair problems, it's crucial to seek advice from a dermatologist or other healthcare expert to identify the root cause and come up with a personalized treatment strategy, according to Goldman's recommendation. “If you're interested in trying oils for hair growth, I encourage you to do so — but remember to use it in moderation and conjunction with other healthy hair practices,” he concludes.
