Ariana Grande, Lady Gaga: damaged hair or androgenetic alopecia?

What you must remember

Lady Gaga and Ariana Grande have publicly discussed the condition of their hair, damaged by bleaching and styling. A broken hair fiber is not androgenetic alopecia: in one case the follicle is intact, in the other it shrinks. This distinction determines the entire treatment plan.

  • Breakage affects the length, alopecia affects the follicle
  • Androgenetic alopecia is the leading cause of chronic hair loss in women
  • It never stops on its own: acting early changes the prognosis

Ariana Grande, Lady Gaga: damaged hair or androgenetic alopecia?

Lady Gaga and Ariana Grande have both spoken publicly about the state of their hair—repeated bleaching, daily styling, and the constant wearing of extensions or wigs. Their accounts have broken the silence on a long-taboo subject, but they describe damaged hair fibers, not hormonal hair loss. This distinction makes all the difference, because it determines what needs to be done.

Damaged hair or androgenetic alopecia: two different things

Hair weakened by chemicals and heat breaks along its length: the fiber breaks, but the follicle remains intact and continues to produce normal hair. Androgenetic alopecia, on the other hand, affects the follicle itself, which miniaturizes and produces increasingly thin fibers.

  • Mechanical or chemical breakage: clean break along its length, follicle intact
  • Androgenetic alopecia: progressive thinning, balding area, miniaturized follicle
  • The two can coexist, and often do.


What I take away from these accounts is the relief they bring to my patients. Speaking publicly about one's hair, as a woman, remains difficult. However, I would never make a diagnosis on someone I haven't examined—and that's exactly what I ask my patients not to do with themselves either.

What is androgenetic alopecia?

This type of hair loss is hormonal and genetic in origin, linked to the sensitivity of hair follicles to DHT, produced from testosterone by the 5-alpha-reductase enzyme. This hormone binds to receptors in the follicle, shortens the growth phase, and triggers miniaturization: the hair grows back thinner and shorter, then stops growing altogether. It is the leading cause of chronic hair loss in adults, and it affects women as much as men—in women, it widens the part rather than receding at the temples.

Signs that point to a hormonal drop

You may be affected if you observe several of these signs:

  • A central line that gradually widens over several years
  • Hair that is noticeably thinner than it was two or three years ago
  • A decreasing density without any noticeable bald patches or broken hairs.
  • A family history of the same type
  • A fall that never completely stops, unlike a reactive fall

If, on the other hand, your hair breaks at the ends, and you regularly bleach or heat it, the issue is not hormonal: it is mechanical.

"I had been using minoxidil for years but with many side effects. I tried this
I tried the serum, thinking it wouldn't work... and yet! The bald spot on the back of my head has clearly filled in. Amazing!

What to do about androgenetic alopecia?

It doesn't stop on its own, and that's what distinguishes it from all other types of hair loss. Acting early is therefore more important than anything: it's much easier to protect a miniaturized follicle than to revive one that has died.

Treatment relies on four mechanisms , and an approach that only addresses one of them quickly reaches its limit: decongesting the scalp, washing at pH 5 to avoid perpetuating inflammation, applying a topical active ingredient to the follicle, and acting from within on the conversion to DHT. All of this must be done for at least three months, the duration of a hair growth cycle.

Before starting anything, make a diagnosis: reactive hair loss, breakage and hormonal alopecia are not treated in the same way.

F.A.Q

Do Ariana Grande and Lady Gaga have alopecia?
They have both publicly discussed hair damage caused by bleaching, repeated styling, and wearing extensions or wigs. Neither has announced a diagnosis of androgenetic alopecia, and no one can make that diagnosis remotely.
What is the difference between broken hair and androgenetic alopecia?
The breakage affects the hair fiber along its length, while the follicle remains intact and continues to produce a normal hair. Androgenetic alopecia affects the follicle itself, which miniaturizes and produces an increasingly thin fiber.
Does androgenetic alopecia affect women?
Yes, it is the leading cause of chronic hair loss in adult women. It manifests as a progressive widening of the central part rather than a receding of the temples, and often worsens during menopause or in cases of PCOS.
Can bleaching cause hair loss?
They damage the hair fiber and cause breakage, which reduces apparent density. They do not miniaturize the follicle. However, repeated traction—from extensions, weaves, or tight hairstyles—can lead to traction alopecia, which is a different mechanism.
How can I tell if my hair loss is hormonal?
Observe the location and duration of the hair loss. Hormonal hair loss is gradual, develops over years, and is concentrated at the part or crown. Breakage affects the lengths of the hair, while reactive hair loss is sudden and widespread. A diagnosis will determine the cause.
Can androgenetic alopecia be stopped?
It slows down, it cannot be cured. Treatment that targets the conversion to DHT slows miniaturization as long as it is continued. The earlier the intervention, the more visible the result.
