Michele Green, MD, a board-certified cosmetic dermatologist based in New York City says the Art Naturals Moroccan Argan Oil Shampoo’s star ingredient is rich in fatty acids and vitamin E, two compounds that moisturize and soothe dry scalp and hair. “Argan oil is a good option for those who experience thin, brittle, and dry hair and want to repair damage while protecting against additional damage from heating tools, harsh chemicals, or the sun,” she says.
Best for Dandruff-Prone Hair: Nizoral Shampoo
Why It’s Worth It: While this shampoo’s main claim to fame is its ability to reduce dandruff and flaking, Dr. Green says its ketoconazole-spiked formula is also helpful in promoting hair growth.

What Causes Hair Thinning?
Connecticut-based board-certified dermatologist Mona Gohara, MD, says that thinning hair can be linked to many things. “It could be from over-processing color, medication, medical conditions like anemia and vitamin deficiency, menopause, or it could just simply be your genetics,” she says.
And more recently, your hair loss may be due to COVID-19, according to Papri Sarkar, MD, a board-certified dermatologist who is based in Brookline, Massachusetts. “Everyone whom I’ve had any contact with throughout the pandemic has seen a huge, huge increase in hair loss,” she says, referring to the many primary care physicians, allergists, and pediatricians who have reached out to her for consults on their telogen effluvium cases.
Telogen effluvium is a form of temporary hair loss from excessive shedding due to a shock to the system, and it “does not discriminate,” says Corey L. Hartman, MD, an assistant clinical professor of dermatology at the University of Alabama School of Medicine. “It can be seen across races, ethnicities, skin types, and hair textures,” he affirmed.
What Ingredients Should I Look For?
New York City board-certified dermatologist Neil Sadick, MD, says an ideal shampoo for thinning hair needs to not only improve the volume of your strands but also encourage the growth and circulation of hair follicles. “Amino acids provide the building blocks to build new strands, while biotin, part of the B-vitamin complex, is required by hair to metabolize amino acids and can help strengthen hair,” he says. Additionally, Dr. Sadick notes that antioxidants, such as vitamin E and ginseng, are beneficial for promoting hair growth “because they reduce free radicals from sun, stress, or overprocessing and have anti-inflammatory properties.”
Ginger King, a New Jersey-based cosmetic chemist and founder of Grace Kingdom Beauty, also recommends looking for shampoos that tout their “styling” capabilities as they work more like styling hairsprays. These shampoos typically contain what King refers to as film formers, which are ingredients like acrylate copolymer. “There are also silk proteins and keratin proteins that can help to add a moisturizing layer for hair to look thicker,” says King.
Lastly, King cautions against products containing silicones if your main concern is thinning hair. “Personally, I am not opposed to the use of silicones in hair care, but for people who have thinning hair, silicones can build up and weigh hair down,” she says.
When Should I See a Doctor About Thinning Hair?
The short answer? As soon as you notice something’s off. It’s pretty normal to lose between 50 to 100 or a little bit above 100 hairs a day,” New York-based board-certified dermatologist Michelle Henry previously told Allure. “Much more than that becomes concerning, and that’s really important to let your dermatologist know.” Try a hair count test, where you count your hair fall each day to see if it’s within that 50 to 100 range.
But even if you haven’t done that, it’s okay to make an appointment with your board-certified dermatologist as soon as you wish. They can look at your scalp, administer relevant blood tests (typically hormone, nutrient, and thyroid panels), and talk to you about your symptoms to see if they align with different types of alopecia.
The sooner you talk about it openly with your medical provider — whether that’s a derm, OB/GYN, primary care provider, or endocrinologist — the sooner they can help get you to a diagnosis and regrowth treatment plan.
In case you need a reminder: Your concerns are valid, and hair loss is connected to so many hormonal and autoimmune conditions that it’s always worth seeking out a medical professional.
