What Causes Hair Loss in Women? Especially at an Early Age Like in Their 20s?

Potential causes of hair loss in young women are:
Having a genetic predisposition to hair lossAutoimmune diseasesChange in hormone levelsMedicationExcessive stressCrash dieting/rapid weight lossPregnancyIron Deficiency
Preventing hair loss can be possible through medical treatments and self-care as well as maintaining a healthy diet. Before recommending any treatment plan for you, your hair loss type and the causes must be identified. This can only be possible with the correct diagnosis made by a specialized doctor. Additionally, determining whether or not the hair loss condition is permanent or temporary and progressive or stable, will also be helpful for choosing the most effective treatment program for you.

With most hair loss cases, in either men or women, there is a genetic predisposition. Environmental factors can worsen or hasten the onset of thinning and shedding due to genes. Common issues include pregnancy, iron deficiencies, surgery, stress, medication side effects and hormonal changes. Through studies on identical twins, excessive sun exposure can also be detrimental to the effect of UV rays which create free radicals in the skin tissue. This can undermine the health of the hair follicles. Also, the use of extensions and tightly pulling hairstyles (e.g. buns, ponytails, dreadlocks) can contribute to traction alopecia, which can be a permanent form of hair loss if the follicles are permanently damaged.

There are many cause of hair loss in women (and men).  There is no way to say why you may be losing hair without an examination by a doctor.

Hello! There are several factors that can cause hair loss in women, especially at a young age. Here is a list of some possible reasons.
Genetics- there may be someone in your family who is suffering from hair loss.Autoimmune diseaseshormone changes Certain MedicationExcessive StressingCrash dieting/rapid weight lossPregnancyIron Deficiency

There are many reasons why hair loss could occur in a women of any age, including in the 20's. Including genetics and it being natural. But assuming it is a condition factors such as stress, poor diet, hormone changes and blood related issues can also be examined. It maybe worth a blood test to check as this may give a root cause to an underlying hair loss condition. This may well be able to be treated. 

Hey there,
Firstly, hair loss doesn't just affect older people. Since your question stresses on age and since there might be other young people in their 20s and 30s who might find this question and come looking for answers, I thought I might start by pointing that out. 
So yes, it is not typically abnormal, and lots of men and women in their teens, 20s and 30s experience hair loss.
Now as to what causes it - it can be hard to answer that because so many factors can cause hair loss. Change in hormones, stress, improper diet, genetics, medical conditions, illness or even a treatment or cosmetic procedure gone wrong (in some cases)!
The best advice would be to find a good hair loss expert in your city and go for an extensive consultation. This will help the doctor narrow down the causes that affect 'YOU' and what you can do to treat the condition.
Hope this helps.

Women in their 20s can experience hair loss. For some women its genetic, its iron deficiency, its diet, or injury, or medication. There are several reasons why you could be experiencing hair loss at such a young age; it's definitely recommended that you visit your doctor for an examination. 

Androgenetic alopecia (aka androgen-related hair loss or female-pattern hair loss or hereditary hair thinning) is the most common cause of hair loss in women. However, there are numerous other important, and common causes, of hair loss that must be investigated in women. A proper history and physical exam will help determine the diagnosis for hair loss. A thorough review of a patient’s medical history (including medications, allergies, family history, and diet) is of utmost importance in identifying the cause of hair loss. A history of menses, pregnancy, and menopause is assessed. Specific hair-related questions that might be asked include: 

-When did the hair loss start?

-Was the hair loss sudden in onset or gradual? If hair loss is sudden, there is likely a disruption of the hair cycle (telogen effluvium) whereas chronic (longstanding) hair loss may indicate an abnormality of the hair follicle (androgenetic alopecia).

-Where have you noticed the most hair loss? When a patient presents for evaluation of hair loss, she may be referring to a single patch of alopecia (alopecia areata) or to extensive hair breakage from use of hair products (hair shaft damage). Patterned hair loss is seen most commonly in androgenetic alopecia

-What is your normal hair care routine? Hair care practices and use of hair cosmetics (i.e. bleaching, permanent waving) can be key factors in determining the cause of hair loss.

A detailed examination of the hair and scalp is performed with good lighting and magnification. Hair distribution over the rest of the body is also assessed to see if there is too little or too much hair in other areas.  

Certain labs can be quite helpful for determining the cause of female hair loss. Screening for thyroid abnormalities, low iron levels and anemia are important during a female hair loss evaluation. An iron panel and complete blood panel (CBC) are useful labs to obtain for women with heavy or long-lasting menses. 





For women with androgenetic alopecia, extensive hormonal evaluation (such as measuring testosterone levels) is usually NOT needed unless any of the following conditions are present: irregular menses, infertility, hirsutism (excess body hair), severe acne, or galactorrhea.



In general, 4 labs that I routinely order in women with hair loss include: CBC, thyroid panel, Ferritin (to measure iron levels), and Vitamin D (which is essential for proper hair growth).

Scalp biopsies can be used to make or confirm a diagnosis of alopecia and can be essential in guiding therapy. 

COMMON CAUSES FOR FEMALE HAIR LOSS

1. Androgenetic Alopecia (AGA), or hereditary hair thinning, is the most common form of hair loss in humans. This condition is also known as male-pattern hair loss or as female-pattern hair thinning. Onset may occur in either sex at any time after puberty and the majority of thinning occurs in the teens, 20s, and 30s. 

2. The second most common cause of female hair loss is thyroid disease (either hypothyroidism or hyperthyroidism). Other common causes of hair loss include inadequate dietary protein, or low levels of vitamin D or iron. 

3. Categories of drugs that may cause hair loss include: anticancer drugs, anticoagulant drugs, anticonvulsant drugs, beta blockers, tricyclic antidepressants, and oral contraceptives. Discontinuation of the medication is usually followed by hair regrowth. Oral contraceptives (birth control) must be selected carefully to avoid progestins with an androgenic effect. 

4. Telogen Effluvium may cause sudden hair shedding. Common causes of Telogen Effluvium include high fever, childbirth, severe infections, severe chronic illness, major surgery, thyroid disorder, crash diets, inadequate protein, and certain drugs. The shedding often starts months after the inciting cause but is always self-limited and reversible if the offending cause is corrected or resolved. 

5. Damage to the hair shaft by improper cosmetic techniques can cause hair breakage. There is little damage from normal dyeing, bleaching, waving or straightening. However, breakage can occur with too much tension during waving; waving solutions left on too long; or improperly neutralized, waving, and bleaching on the same day or too frequently. Other causes of hair breakage include excess tension in braids, ponytails, or cornrows.

6. Alopecia Areata is an autoimmune disease that affects almost 2% of the population in the United States. Inflammatory cells target the hair follicle, thus preventing hair growth. Typically a small round patch of hair is noticed; this patchy hair loss may regrow spontaneously. In other cases there can be extensive patchy hair loss, and in rare cases, there is loss of all scalp and body hair (Alopecia Areata Universalis).

In summary, there are multiple causes for hair loss in women. In order to determine the exact cause of hair loss, a complete review of the patient’s medical history, detailed hair and scalp exam, and laboratory test(s) are necessary. Appropriate treatment and counseling can then be tailored to each patient’s needs. 

First, go get a blood test:   CBC, CMP, TSH, T4, ferritin. Anemia , iron deficiency, and hypothyroidism are common causes of hair loss that can be treated fairly easily.   If they are within normal limits, then start to look at stress level,  endurance exercises, and hormones can be an issue.

Although women can, and do, suffer from genetic pattern hair loss similar to that experienced by men, women’s hair loss can also be triggered or even worsened by a variety of medical conditions, ranging from hormonal fluctuations to thyroid problems to vitamin deficiencies. It may also be exacerbated by environmental factors like stress, diet, a woman’s choice of birth control, or even the way that she wears her hair. Because the issues surrounding women’s hair loss are so complex, they often require highly specialized methods of diagnosis and approaches to treatment. That is why it is vital, in all cases of women’s hair loss, to seek out a hair restoration specialist for a comprehensive, individual diagnosis.

In younger women, particularly those in their twenties, one of the more common causes of hair loss is telogen effluvium. Any physiological shock to the body, such as a traumatic injury, major surgery, or even a crash diet can potentially trigger this condition, which causes a disproportionately large number of hair follicles to enter the telogen phase all at once so that they are all lost at once to the natural shedding process weeks or months after the initial triggering event. Further, other hormonal shifts in the body, like those that occur both before and after the birth of a child, can also cause women to experience drastic changes in the thickness and density of their hair.

Fortunately, patients do not go completely bald from telogen effluvium and the hair loss they experience is usually only temporary. If the external cause is correctly identified and dealt with, the follicles go right back to producing hair normally, and in most cases those affected recover as much as 90% of the hair lost. To promote hair growth faster, we can prescribe certain compounded medications and supplements. Red light therapy, which uses focused light to increase the energy production around the hair follicles and awaken cells from dormancy into an active growth phase, has also proven to slow the progression of hair loss and, in some cases, to help new hairs grow. Finally, we have also found that platelet rich plasma, a specially prepared concentration of the patient’s own blood, can help accelerate the transition of the hair follicle from the dormant telogen state back to the actively growing anagen state, not only accelerating regrowth, but also potentially reducing the necessary recovery time after hair restoration surgery.





Again, every woman is unique and every case of women’s hair loss requires its own diagnosis. That’s why we recommend that every one of our patients undergo a comprehensive diagnostic analysis of their hair loss so that we can determine what form of treatment is right for their specific needs.
