Hair Serums Never Worked on My Thin Hair—Then I Tried This Growth-Boosting One

What causes hair thinning and hair loss?

Geria says that hair thinning can be influenced by multiple medical and lifestyle factors, including stress, certain medications, hormonal changes (like during menopause and pregnancy), and even hairstyling practices. “Hair thinning is a common issue that can happen naturally in women with age,” he says. “As women age, their hair follicles can become less productive, decreasing hair density and thickness.” 

Can you prevent hair loss?

Nathan says that there are different types of hair loss that are characterized by different traits: “Hair loss is multifactorial, so no single treatment will be a complete cure.” However, there are some steps you can take to prevent it. “You may help to prevent or slow hair thinning by making sure to take care of yourself by prioritizing sleep and finding ways to manage stress. Consume a varied diet that is rich in fruits, vegetables, and seeds, all of which contain antioxidants,” she says. “Do not forget your protein! Adequate protein intake is so important for hair health. Hair is made of protein, and the body needs adequate protein stores to grow new hair. Experts recommend 40 to 60 grams of protein each day for healthy women who are experiencing hair loss.” 

Geria agrees, adding that your hair routine can make a big difference. “Excessive heat styling can damage hair and lead to hair thinning. Always use a heat-protectant spray, and keep the heat at a moderate temperature,” he says.

He also recommends washing your hair regularly (no skipping shampoo!). “Regularly washing your hair with a mild shampoo can help prevent the buildup of oils and products that can clog hair follicles and cause hair thinning,” Geria says. Finally, he recommends using a wide-toothed comb to brush your hair, as it will prevent pulling and breaking.
