We Rebuilt The Hat
Hair restoration surgeon. Oxford. Northwestern. UCLA.
Dr. Robert Dorfman has spent his career seeing what everyday hats do to hair and skin.
As a hair transplant and aesthetic surgeon at Done by Dorfman in Beverly Hills, he sees the same story every day: patients who wear hats, patients who love the way they look in hats, and patients whose hair and skin have paid the price for it. The friction. The heat trap. The hairline recession that builds slowly over years of daily cotton-lined wear. He joined Hatsy as a founding partner because he found the solution — and he wanted to put it inside every hat.

“The silk-lined interior is the single best thing a daily hat wearer can do for their hair and skin. Full stop.”
20,000+ patients so far
Traction alopecia. Acne mechanica. Hairline recession from friction. These are not rare conditions in Dr. Dorfman’s practice — they are some of the most common things he treats. And in many of those cases, daily hat wear against cotton and synthetic linings is part of the picture.
The sweatband in a standard hat touches the hairline for every hour it is worn. Over months and years, the mechanical stress from that contact — the friction, the heat, the moisture trapping — can add up to the kind of wear that brings people to a hair restoration clinic. Dr. Dorfman has seen it thousands of times. He knows the timeline. He knows the pattern.
The same standard he uses in his clinic.
Dr. Dorfman’s clinical work is built around understanding how mechanical forces affect hair follicles and skin. Traction, friction, heat — these are the enemies of a healthy hairline. Silk, specifically Grade 6A Mulberry Silk, is the only fabric that addresses all three simultaneously.
Its surface is smooth enough to produce near-zero friction against the hair shaft. It is naturally thermoregulating, maintaining a stable temperature under the hat. And it does not absorb moisture the way cotton does, so sweat moves away from the scalp rather than sitting against it. These are not marketing claims — they are the same properties Dr. Dorfman looks for when evaluating any material that will contact the scalp and hairline of his patients.
When he evaluated the Hatsy construction — six silk components, hand-stitched, using only Grade 6A — he set one condition for his involvement: the standard could not change. It has not.
Four rules inside every hat.
- 01Grade 6A mulberry silkThe smoothest grade, on every surface that touches you.
- 02Six silk componentsLining, sweatband and strap: silk wherever the hat meets hair or skin.
- 03Hand cut, hand stitchedNo seams or rough edges where the hat rests on your hairline.
- 04The standard does not changeDr. Dorfman’s one condition for joining Hatsy.
Robert Dorfman, MDCo-founder, Hatsy
“For patients who wear hats daily, switching to a silk-lined hat is one of the first things I recommend. It is a preventive measure that costs nothing compared to what it prevents.”
Not an endorsement. A co-founding standard.
Dr. Dorfman is not a spokesperson for Hatsy. He is a co-founder. There is a difference. His involvement means the silk specification, the construction standard, and the quality control are all set by someone whose livelihood depends on getting it right for the people who wear these hats every day.
He helped set the standard for what goes inside every Hatsy hat: the grade of silk, every place it touches you, and how it’s stitched. If a hat doesn’t meet that standard, it doesn’t ship.
