Currently, it is not clear if androgens (male sex hormones) play a role in FPHL, although androgens have a clear role in male pattern baldness. The majority of women with FPHL have normal levels of androgens in their bloodstream. Due to this uncertain relationship, the term FPHL is preferred to ‘female androgenetic alopecia’.
Addressing shortfalls through diet and supplements: Does it help hair growth?
Your clinician might prescribe anti-inflammatory medications, like corticosteroids, if hair loss seems related to an autoimmune condition. It’s important to keep in mind that hair growth is a complex process and multiple tests may be needed to understand what is causing your hair loss. A biopsy may also be taken if it is initially very unclear what the root causes may be. In addition to losing hair on the scalp, some people with alopecia areata lose hair from their eyebrows, eyelashes, or other parts of the body. There are several types of hair loss, some are common and some are rarer, and each with different underlying causes. Low-level laser therapy or photobiomodulation is also referred to as red light therapy and cold laser therapy.
What questions should I ask my healthcare provider?
It’s typical to lose between 50 and 100 hairs a day, according to the American Academy of Dermatology (AAD). With about 100,000 hairs on your head, that small loss isn’t noticeable. New hair normally replaces the lost hair, but this doesn’t always happen. Treatment for traction alopecia is elimination of physical traction or stress to the scalp. Scalp biopsy is indicated when alopecia persists and diagnosis is in doubt. In cases of suspected cicatricial alopecia, specimens should be taken from areas of active inflammation, typically at the border of a bald patch.
Prescription oral medications
However, even in areas of complete baldness, these medications can help limit further progression in other areas of hair loss where complete baldness has not entirely set in. The precise biological mechanisms by which microbiotas influence AGA development remain unclear. The microbiota plays a major role in the endocrine system by interacting with estrogen, androgens, insulin, and other hormones (Qi et al., 2021).
Another oral option that is more tried and true than oral minoxidil is finasteride, known by the brand name Propecia, which is approved by the FDA for hair loss treatment in men. This medication can cause birth defects, so it may be considered for postmenopausal women, Browning points out. In the latter case, Propecia is offered as an off-label prescription, just like oral minoxidil is for hair loss in general. Minoxidil works by stimulating hair growth and preventing new hair loss, according to the American Academy of Dermatology (AAD). You’ll have to use it consistently for three to six months before seeing the benefits. Even when your hair grows back, you’ll still have to apply minoxidil daily as directed, otherwise it will begin to thin again.
The resting period, or telogen phase, follows catagen and lasts for three months. Following the telogen phase, the next anagen phase begins, and the old hair is dislodged and falls out to make room for new hair to begin growing in its place. While it’s challenging to achieve full regrowth, some treatments, like minoxidil and finasteride, may stimulate hair regrowth in some individuals.³² However, the extent of regrowth can vary from person to person. Remember, consulting a healthcare professional is crucial for personalized guidance.

What role does heredity/genetics play in the male pattern hair loss?
Everyone is born with a fixed number of hair follicles on the scalp that produce hairs throughout life. Hair grows from the base of the follicle at a rate of about one centimetre a month for about three years. It sits dormant in the follicle for a three-month phase called telogen. After telogen, the hair follicle undergoes another anagen phase to produce new hair that grows out of the same follicle.

Other oft-used drugs include finasteride (Propecia) and spironolactone. If you have scarring alopecia or alopecia areata, your doctor may recommend an anti-inflammatory medication such as the JAK inhibitor Olumiant (baricitinib) to help tamp down your immune system. Just as in men, the hormone DHT appears to be at least partially to blame for the miniaturization of hair follicles in women suffering with female pattern baldness. Platelet‐rich plasma (PRP) is another alternative treatment for AGA with the benefit that it is performed without any patient responsibilities. PRP is generally indicated for patients with early‐stage AGA, as intact hair follicles are present and a more significant hair restorative effect can be achieved. During the procedure, approximately 10–30 mL of blood are drawn from the patient's vein and centrifuged for 10 min in order to separate the plasma from red blood cells.
In fact, only one gene that codes for the androgen receptor has been clearly linked to AGA so far. Accordingly, although a family history may be helpful, the expression of hair loss is so variable that it is not always predictive of how you will advance in your hair loss. For example, your father may have a full head of hair, and you may be rapidly balding. Since there are epigenetic influences, that is, environmental effects, that can retard or accelerate hair loss, even genetically identical twins may manifest different degrees of hair loss.
Your hair will remain on your head where it belongs unless hormone imbalance, disease, or some other condition occurs. That condition may be as simple as having a gene that makes you susceptible to male or female pattern baldness or one of the forms of alopecia areata, or it may be as complex as a whole host of diseases. If you have a close family member with male or female pattern hair loss, you’re likely to be at risk for it as well.
Many people that have male pattern baldness accept it as part of the aging process and don’t see a healthcare provider. Reach out to your healthcare provider as soon as you notice signs of male pattern baldness, especially if it causes stress, anxiety or depression. Although the condition is considered a noninflammatory form of hair loss, a superficial, perifollicular, inflammatory infiltrate is noted at times. Whether sleep deprivation can cause hair loss by some other mechanism is not clear. However, its large size and lipophilic nature contribute to it remaining on the scalp and preventing systemic absorption.
FPHL presents quite differently from the more easily recognisable male pattern baldness, which usually begins with a receding frontal hairline that progresses to a bald patch on top of the head. It is very uncommon for women to bald following the male pattern unless there is excessive production of androgens in the body. Female pattern hair loss (FPHL) is a distinctive form of diffuse hair loss that occurs in women with androgenetic alopecia.
Individuals experiencing hair loss often suffer from a diminished quality of life, including reduced self-confidence and heightened feelings of depression (Lee et al., 2002; Yeo et al., 2014; Marks et al., 2019). Consequently, the effective management of hair loss plays a crucial role in improving people’s overall wellbeing. To enhance our ability to prevent and treat AGA effectively, it is essential to acquire a more comprehensive understanding of the underlying mechanisms that contribute to its development. Nevertheless, the precise cause behind the escalating incidence rate of AGA has yet to be fully elucidated.
