Choosing a hat that doesn’t fit well, isn’t suited for the weather, or doesn’t match hair type can lead to hair problems and even hair loss. This view comes from dermatologist and trichologist Anastasia Mareeva of the Likato Professional brand, who explained the risks to readers.
Exposure to freezing temperatures can harm hair quality. Hair may become more porous, brittle, dry, and prone to split ends, which can shorten its length and contribute to thinning. The doctor notes that a poorly chosen hat can have a similar effect on scalp health and hair integrity.
“A frequent mistake is buying a hat that is the wrong size, particularly one with a stiff base or brim. People also assume one hat works in every season and climate. In both cases, the result is hair and scalp degradation, and over time, possible thinning or bald patches,” Mareeva said.
The trichologist advised having several hats for different temperatures. Thick wool hats suit cold days, while lighter fabrics are better for milder weather. Those with long hair can protect strands from wind damage by using a hood. When selecting a hat, it helps to consider the wearer’s hair type.
“Small blisters, pimples, peeling, crusting, sweating, increased sebum, itching, burning, or pain can occur from a hat that doesn’t fit or vent properly. Dense foreheads or tight hats can compress the scalp, and brittle, curly, or frizzy hair may break under pressure, reducing volume and length,” the trichologist explained.
The expert advised measuring head size with a flexible tape, wrapping it around the head about 2 cm above the eyebrows. The measurement should guide the purchase; otherwise, there is a higher risk of problems arising later.
“Men are especially likely to experience issues: wearing tight hats with hard edges around the neck and the back of the head can cause bald spots where friction is greatest, along with minor to moderate inflammatory changes that may require treatment,” Mareeva emphasized.
She added that staying in a tight hat for extended periods can trigger micro-inflammation around hair follicles due to tension and sustained pressure on the scalp.
“Additionally, thick woolen or synthetic hats can worsen scalp conditions by creating a greenhouse effect. Excessive sweating, increased sebum, crusting, and peeling can occur, along with inflammatory marks, potentially leading to hair loss,” the expert concluded.
The trichologist also warned against wearing hats indoors or in crowded spaces like subways. Overheating can worsen scalp conditions, impede hair growth, and negatively affect hair quality, potentially contributing to hair thinning down the line.
The discussion also touched on the broader health context, including how lifestyle and environmental factors can influence hair health and recovery over time.
