A 16-year-old girl presents to a pediatrician with significant distress surrounding acute hair loss. She says for the past few weeks she has been losing clumps of hair on her pillow, in her shower, and in her hair brush. She typically washes her hair every day, but recently has decreased to once weekly out of a desire to mitigate the loss. She is only combing with a wide-toothed comb, and does not use any styling products. She is very anxious and upset about her loss of hair. She is accompanied by her mother and two younger sisters.
Her past medical history is significant for rheumatic fever as a child, but she does not take any medications or supplements regularly. There is no family history of hair loss. She is the eldest of five siblings, and describes her family as involved and Catholic. She is in the 11th grade and is a good student, planning to attend college and pursue studies in literature after she graduates. She eats most of her meals at home (except for school lunches), and has several close friends. Her mother describes her as bookish.
On physical exam, the patient is appropriately developed for her age, and visibly anxious. A hair pull test reveals five and then six hairs on sequential trials. She states that she last washed her hair yesterday. There is some thinning noted over the bitemporal regions of the scalp, but otherwise her hair is relatively thick and dense. There are no areas of frank alopecia, and no scarring is noted on the scalp. Her review of systems is otherwise fully negative.
Differential Diagnosis
Lupus
Trichotillomania
Telogen effluvium
Androgenetic alopecia
  • Lupus: In systemic lupus, hair loss/thinning is often described by patients. Serum ANA is typically positive, and by review of systems or laboratory analysis, the patient should also meet other criteria for lupus. A scalp biopsy may help confirm the diagnosis if clinically suspicious.
  • Trichotillomania: This condition is defined by patients (either consciously or not) pulling out their own hair, often in conjunction with anxiety or depression. In a more subtle version of this condition, patients may pull or twist their hair habitually, gradually leading to loss. Patterns of hair loss are typically more focal.
  • Telogen effluvium: The hair growth cycle consists of three phases: anagen (active growth), catagen (transition/resting), and telogen (shedding). Following severe stress, illness, hospitalization, surgery, or pregnancy, patients may notice dramatic shedding of telogen hairs. This typically occurs approximately 3 months after the inciting event. Laboratory workup should be within normal limits, and while this is typically a clinical diagnosis, a scalp biopsy may reveal greater proportions of telogen hairs. A hair pull test should be performed on a day when the patient has not shampooed, and a positive result would be the extraction of 6 or more hairs out of a group of 40 hairs pulled. While typically a self-limiting problem (with resolution of normal hair thickness and growth within 36 months), some cases of telogen effluvium can become chronic and unmask an underlying tendency towards androgenetic alopecia (Fig. ).

  • Androgenetic alopecia: Commonly referred to as male pattern baldness, androgenetic alopecia can occur in female patients as well, and can be seen in younger age groups. Male pattern is typically more over the bitemporal region and vertex, whereas female pattern preserves the anterior hairline and begins as widening of the part, progressing to diffuse thinning over the top of the scalp. Thyroid function, iron status, and vitamin D levels should be assessed and optimized. The etiology of androgenetic alopecia is thought to be multifactorial, with components of genetics, hormone levels, and environmental factors playing a role. Onset is usually insidious and progressive.
Further Workup
The patients family is asked to return to the waiting room, so that the doctor can perform a private examination. Her mother is initially resistant but later acquiesces. The pediatrician then takes the opportunity to spend a few more minutes on the patients history, and asks if anything particularly stressful has occurred in the last several months. The patient denies anything out of the ordinary. Her doctor then asks if she is sexually active, and the patient breaks down in tears. She admits to having a boyfriend of which her parents are not aware, as they are quite controlling and resistant to dating, and states that she had protected sexual intercourse for the first (and only) time 3 months ago. She has been feeling incredibly guilty and anxious since that event, to the point that her boyfriend broke up with her last week.
A serum vitamin D level, CBC, iron studies, and TSH are all found to be within normal limits. Beta-HcG and ANA are negative.
Diagnosis
Telogen effluvium
Conventional Treatment Options
  • Time : The natural course of telogen effluvium is resolution, typically within 36 months, although some cases can become chronic (particularly if the patient has underlying androgenetic alopecia which becomes unmasked). Most often, however, if the inciting factor was an isolated event or occurrence, then full resolution without intervention is typical.
  • Counseling : If telogen effluvium is secondary to (or accompanied by) severe stress or anxiety, referral for professional counseling may help break the vicious cycle.
  • Minoxidil : Topical minoxidil is available in 2 and 5 % formulations, and while the approved indication is for androgenetic alopecia, may help promote hair growth in telogen effluvium as well (use is off-label). One caution with minoxidil is that, for androgenetic alopecia, cessation of treatment leads to shedding of any regained hairsthis phenomenon, however, is not clear-cut in acute telogen effluvium but remains a possibility of which patients should be aware. Additionally, minoxidil is available in solution and foam formulations, and many patients report irritation with the former (likely from the propylene glycol in the vehicle).
Integrative Treatment Options
  • Avoidance of products containing parabens, sulphates, and phthalates : To generally support healthy hair and discourage breakage of newly growing strands, it is advisable to use hair care products that are as free of potential irritants and carcinogenic or endocrine-disrupting chemicals as possible.
  • Eucalyptus oil : The benefits of eucalyptus oil are more in supporting the elasticity and shine of existing hair, rather than promoting new hair growth [], but this effect in turn can improve the patients perception of their hair and reduce the surrounding anxiety of telogen effluvium. Eucalyptus is presently available in commercial root awakening formulas.
  • Coconut oil : Contrary to some cultural beliefs, coconut oil does not demonstrate the ability to grow new hair, but rather supports the health of that which is already existing. This oil has the highest ability to penetrate inside the hair shaft based on low molecular weight and linear structure, thus preventing protein loss and improving hair strength and appearance [].
