Hair Loss Doctor Explains the Surprising Habits and Mistakes That Cause Hair Loss in Women
From the hair care that you use to the way you brush your hair, get some insight into why you’re dealing with thinning hair
The reasons for hair loss and thinning run the gamut. You could be dealing with vitamin deficiencies; your stress levels can lead to shedding; your genetics come into play. But there are some things that you might be aware of, or not, that can also give insight into why you’re losing hair or noticing a loss in density and/or some sparse spots. That’s why we turned to a top hair loss doctor to learn what causes hair loss in women and some of them are surprising. Read on to discover the causes of hair loss in women and how to treat it no matter the type of hair loss.
What causes hair loss in women?
“There are several common habits and mistakes that can contribute to hair loss, often without people even realizing it, says says Alan J. Bauman, MD, ABHRS, IAHRS, FISHRS, Founder, CEO & Medical Director of Bauman Medical Hair Transplant & Hair Loss Treatment Center. To see and learn more about them, keep scrolling.
Causes of hair loss in women: Trichotillomania
“One significant habit to be aware of is trichotillomania, a compulsive hair-pulling disorder,” says Dr. Bauman. “People with trichotillomania may find themselves repeatedly pulling out hair from their scalp, eyebrows, or other areas, leading to noticeable hair thinning or bald patches. It’s a condition that often requires professional support, including behavioral therapy, to manage effectively.”
Causes of hair loss in women: Improper scalp care
“Another major mistake is neglecting scalp health. An unhealthy scalp — whether due to buildup from products like dry shampoo, excessive oil, or lack of proper cleansing causing inflammation — can hinder hair growth and contribute to hair thinning,” explains Dr. Bauman.
Causes of hair loss in women: Using harmful hair care products
To add to what’s mentioned above, the hair care that you use also matters. “The hair care products you use can have a significant impact on both hair loss and hair growth,” says Dr. Bauman. “The right products can support scalp health and strengthen hair, while the wrong ones can contribute to damage and even exacerbate hair loss.”
For instance, using a high-quality shampoo that targets the root causes of hair thinning, such as DHT (dihydrotestosterone) buildup, can make a big difference, notes Dr. Bauman. He goes on to say that at his practice, he often recommends a DHT-blocking shampoo specifically designed to help reduce the impact of DHT on hair follicles, which is a common cause of hair loss.
“On the other hand, certain products can be harmful if overused or not used correctly,” says Dr. Bauman. “Dry shampoo is a good example — while it can be a convenient solution for refreshing hair between washes, overuse can lead to a buildup on the scalp. This buildup can clog hair follicles, hinder healthy hair growth, and even contribute to scalp irritation and inflammation. It’s important to use dry shampoo sparingly and ensure that you thoroughly cleanse your scalp with a gentle, sulfate-free shampoo regularly to prevent any potential negative effects.”
Also, frequent use of products containing harsh chemicals, like sulfates and parabens, can strip the hair of its natural oils, leaving it dry, brittle, and more prone to breakage, says Dr. Bauman. “Opting for hair care products that are free from these ingredients and specifically formulated to support scalp and hair health, such as our SOOTHE Shampoo & Conditioner, is a smart choice.”
Causes of hair loss in women: Frequent hot tool use and chemical treatments
“Over-styling, particularly with heat tools like flat irons, curling wands, and blow dryers, can weaken the hair shaft, leading to hair breakage and thinning over time,” says Dr. Bauman. Additionally, “frequent use of harsh chemical treatments, such as coloring, perming, or relaxing, can damage both the hair and the scalp, making the hair more prone to shedding.”
Causes of hair loss in women: How you brush your hair
Hair brushing and styling are critical components of your hair care routine, and how you approach them can significantly influence your hair’s health and longevity,” explains Dr. Bauman. “The way you brush and style your hair can either help maintain its strength and reduce hair loss or, if done incorrectly, contribute to breakage and thinning.”
“When it comes to brushing, it’s important to be gentle, especially when your hair is wet, as wet hair is more fragile and prone to breakage,” says Dr. Bauman. “Using a wide-tooth comb or a brush with soft, flexible bristles can help minimize tension on the hair shaft and reduce the risk of pulling out or breaking hairs. Start by detangling the ends and gradually work your way up to avoid putting unnecessary stress on the hair.”
Causes of hair loss in women: Tight hairstyles and extensions
Wearing tight hairstyles, like ponytails, braids, or buns, in addition to the overuse of hair extensions can cause traction alopecia, a form of hair loss that results from the constant pulling on the hair follicles, notes Dr. Bauman. “It’s important to vary your hairstyles and avoid consistently tight styles to minimize stress on the hair.”
Causes of hair loss in women: Ignoring signs of hair loss
“Another mistake is not addressing early signs of hair loss, says Dr. Bauman. “Many people ignore the initial signs, thinking they’re normal, but early intervention is crucial. At Bauman Medical, we emphasize the importance of regular scalp evaluations and utilizing diagnostic tools like HairMetrix — an AI-powered microscope that measures exact hair density and hair caliber — to help diagnose and track hair loss changes.”
Causes of hair loss in women: Your lifestyle
“Finally, lifestyle factors play a significant role — chronic stress, poor nutrition, and lack of sleep can all exacerbate hair loss,” adds Dr. Bauman. “Not getting enough essential nutrients, particularly those that support hair growth, can weaken the hair over time. Incorporating a balanced diet, proper supplementation, and stress management techniques can help mitigate these effects.”
“By avoiding these common pitfalls and being proactive about hair health, including seeking help for conditions like trichotillomania, you can significantly reduce the risk of hair loss and maintain healthier hair overall,” explains Dr. Bauman. “[And] if hair loss progresses even after taking these steps, you may need more powerful treatments. ‘Time equals follicles’ so the longer you wait, the more extensive your hair loss may become.” That’s why he recommends seeing a board-certified hair restoration specialist as soon as possible.
