If you’ve noticed more strands in your brush or a wider part staring back at you in the mirror, the problem may be your scalp—not strands. If you’re dealing with itchiness or scalp irritation, it could be contributing to hair loss. A healthy scalp is the foundation for healthy hair, and dermatologists say the right scalp treatment for hair growth can make a real difference in the long term. Most of the fixes are simple, affordable and something you can start today. Keep scrolling to see the best treatments for hair loss to help regrow hair faster.
How scalp issues can trigger hair loss
Scalp inflammation is one of the most common culprits behind thinning hair. “Hair loss caused by the physical stresses to the scalp of styling (i.e. which can cause scalp inflammation) has become one the most common causes of hair thinning I see in my practice—and it’s on the rise,” says Francesca Fusco, MD, a New York City dermatologist who specializes in female hair loss. Chemical treatments followed by heat styling, tight ponytails and hairpieces can all inflame follicles and lead to traction alopecia, or thinning at the forehead, temples and nape of the neck.
An itchy scalp adds another layer of trouble. Seborrheic dermatitis, dandruff, psoriasis and even head lice can send you scratching, and the scratching itself can trigger shedding. “Constantly scratching the scalp can lead to damage to the hair follicles,” Michele Green, MD, a board-certified cosmetic dermatologist in NYC, explains. “Once the hair follicles are damaged, they are unable to produce healthy hair strands.”
Hormones matter, too. Women see a 75 to 80 percent drop in estrogen during menopause, while testosterone drops only about 20 to 25 percent. A shift in ratio that can affect scalp health and accelerate female pattern hair loss.
Why nourishing your scalp encourages hair growth
When your scalp is inflamed, flaky or starved of nutrients, healthy hair growth suffers. Female hair loss specialist Mary Wendel, MD, founder of Medi-Tresse, points to the scalp microbiome—”an ecosystem of microscopic organisms like bacteria and fungi” that, when balanced, protects the scalp and creates a healthy environment for hair to grow.
Nutrition plays a starring role. “Your hair is fighting for the same vitamins and nutrients as your vital organs. So when you are deficient, your hair loses out,” Dr. Wendel says. That’s why crash diets and GLP-1 medications so often trigger shedding.
Circulation is the other half of the equation. Increasing blood flow to the scalp delivers oxygen and nutrients directly to the follicles, and “scalp massages also aim to remove dead skin cells and product buildup on the scalp to allow for decreased scalp irritation and better absorption of hair growth serums and other products,” Dr. Green says.
The 4 best scalp treatments for hair growth
These treatments nourish your scalp to promote hair growth over time. Here’s what our experts recommend:
Swap your shampoo
For a flakey, itchy scalp, look for a medicated shampoo with 1% pyrithione zinc, such as Selsun Blue Itchy Dry Scalp or Head & Shoulders Classic Clean Daily Shampoo. “In addition to easing inflammation and flakes, zinc pyrithione is a humectant that supports skin healing,” Dr. Fusco says.
For an oily scalp, a clarifying shampoo with salicylic acid—such as Briogeo Scalp Revival Dandruff Relief Shampoo—deep-cleans buildup. And for dry hair, a moisturizing formula such as Bangin Hair Juicy Reset Shampoo used less often works best.
Feed your follicles
Aim for an anti-inflammatory diet full of antioxidant-rich fruits and vegetables and part of your hair-loss treatment strategy. “Nutrients such as vitamin D, iron and zinc have proven benefits,” Dr. Wendel says. A quality supplement can help fill gaps. Dr. Wendel recommends her own Tresse line, while dermatologist Jennifer Gordon, MD, of Westlake Dermatology, personally swears by Nutrafol, formulated for women over 45.
Try a scalp massage for hair growth
A soothing, four-minute daily scalp massage has been shown to help stimulate hair growth naturally. Use the pads of your fingertips—not your nails—to massage your scalp in small circular motions. A study in Dermatology and Therapy of women with thinning hair found that massaging twice daily, 12 hours apart, reduced shedding and boosted regrowth.

Rethink your styling
A few smart moves can help protect your hair—and scalp—in the long haul. Skip shampoo 24 hours before any chemical service so a protective layer of sebum can form, celebrity hairstylist Tabatha Coffey advises. Trade tight ponytails for loose chignons, swap heavy sewn-in extensions for lightweight clip-ins and always choose the lowest heat setting on your blow-dryer, all of which help reduce the risk of breakage and support healthy hair growth.
When it’s time to call a pro to treat hair loss
Give your new scalp treatment for hair growth a fair shot, but if you don’t see regrowth within three months, make an appointment with a dermatologist. Prescription options like oral minoxidil, platelet-rich plasma (PRP) therapy, hormone treatment or, in advanced cases, surgical transplantation can help you get back on track. Fuller, healthier hair really does start at the roots—and now you know exactly where to begin.
