Causes of Hair Thinning

To start, it’s helpful to address why you might be experiencing thinning in the first place. “A big cause nowadays of telogen effluvium (diffuse temporary hair loss) is stress,” says trichologist Angela Onuoha. She additionally cites COVID, chronic infections, certain medications, metabolic changes, hormonal irregularities, postpartum, and diet as potential causes. “It occurs due to a disturbance of the hair cycle; this causes the hairs to fall out prematurely,” Onuoha explains. “The positive thing is that, in the short term, telogen effluvium is rarely permanent, meaning that the hair will grow back eventually.”

Solutions for Hair Thinning

Onuoha explains that identifying the cause of thinning can inform your treatment. “The priority is to normalize the hair cycle again,” she says. “Regrowth usually begins three to six months after treatment.” Essentially, you want to ensure your hair is in the best health possible—this means alleviating signs of damage. According to her, this can happen through bond repair treatments or ingredients like peptides (which have been “shown to help with slowing down hair loss and improve both the quality and density of the hair over time”), azelaic acid (“which helps reduce inflammation”), pyridoxine HCL, and zinc PCA. Celebrity hairstylist Peter Burkhill recommends anything that can encourage hair to grow back faster and thicker—from DHT blockers for men or iron, biotin, and caffeine supplements for women. “You want to avoid anything with silicone or sulfates as they suffocate the scalp; it’s a little bit like wearing a hat!” he says.

That being said, Onuoha details that the best shampoo for thinning hair is often lightweight so as not to weigh the hair down and is enriched with exfoliants to remove excess buildup on the scalp. These properties combined allow for hair that looks fuller and healthier. Here, we’ve tapped five hair experts for the best shampoos to consider based on your hair type—plus a couple of favorites that have earned Vogue editors’ stamps of approval.

Moisturizing lilly pilly and oat-derived peptides also make up the formula.
• Best for: Some extra body and bounce.

How to Style Thinning Hair

Your styling methodology can also make (or break) your strands—meaning avoid tension and friction as much as possible. To do so, Onuoha recommends using detangling sprays, leave-in conditioners, oils, and serums to create a protective film around hair strands.

Dr. Hardik Doshi, lead surgeon at Ample, a New York City-based hair restoration clinic, suggests using the below products. However, he strongly encourages anyone dealing with hair thinning to consult with a professional stylist or hair-care specialist before switching up their routines.

Some other options include volumizing stylers by Aveda or Philip Kingsley. To incorporate one of these, James says: “Use sprays to lift your roots whilst using the comb to tease and create texture.” Otherwise, he leaves us with two pro tips. The first: “Roller setting your hair instead of doing blowouts will create volume giving the illusion of fuller hair.” For afro hairstyles, consider “twist outs using minimal heat sealed with a lightweight product.”

More Solutions for Thinning Hair

If after three to six months, you have yet to notice a difference in hair density, you may need to switch up your regimen. Dr. Doshi suggests speaking with a specialized MD who can develop a treatment plan that includes a mix of over-the-counter (OTC) and prescription products. “OTC options, like minoxidil-based topicals and ketoconazole shampoos, enhance blood flow and scalp health, while nutritional supplements with biotin, vitamin D, and iron support overall hair health,” he explains. “Prescription medications like finasteride for men and topical spironolactone for women inhibit DHT, linked to hair thinning.” You can also opt for in-office treatments like platelet-rich plasma (PRP) therapy to help stimulate growth.
