Study Notes
Androgenic Alopecia Overview
- Often does not require treatment, but may be pursued for cosmetic reasons.
- Treatment decisions depend on patient preferences, side effects, cost, and adherence potential.
- Primary goals are slowing hair loss and stimulating regrowth; typically, treatments show effects in 6-12 months.
- Long-term commitment is essential, possibly for years; realistic expectations should be set through counseling.
Diagnosis of Hair Loss
- Critical factors include age of onset, stress associations, visible shedding, location of thinning, duration, and hair care practices.
- Medical and family histories are essential in assessing hair loss.
Female Pattern Hair Loss (FPHL)
- Approximately 40% of women exhibit hair loss by age 50; fewer than 45% maintain a full head of hair by 80.
- Less frequent in Asian women compared to Caucasian women.
- Genetic predisposition is a significant factor; androgens' roles remain uncertain as most women have normal levels.
Minoxidil Treatment
- Mechanism of action is unclear but functions as a vasodilator, enhancing hair growth phases.
- Administered as a topical solution (5% foam or lotion) twice daily for 6-12 months.
- Initial shedding may increase within the first 2-6 weeks; regrowth typically evident after at least 4 months.
- Side effects may include erythema, itching, and scalp irritation; hypertrichosis is rare.
Finasteride for Male Pattern Hair Loss
- A 5α-reductase inhibitor reducing testosterone conversion to DHT, thus preventing follicular miniaturization.
- Dosage options include 1mg daily or 5mg weekly; effective benefits might take 1-2 years.
- Continuous use is critical, with a stop recommendation if no benefits are seen after 12 months.
Spironolactone for Female Hair Loss
- Doses range from 50-100 mg daily, possibly increasing to 200 mg after 6-12 months if necessary.
- Functions as an aldosterone antagonist that blocks androgen effects and synthesizes inhibition.
- Contraindicated in pregnancy; potential side effects include dizziness, diuresis, and menstrual irregularities.
- Requires regular monitoring of blood pressure and biochemical functions.
Trichotillomania
- Classified as an impulse control disorder marked by compulsive hair-pulling from various body parts.
- Often resolves in children with age, though can arise from home or school-related stress.
- Treatment involves psychological referral, habit reversal therapy, and cognitive behavioral therapy.
Counseling Points for Hair Loss Treatments
- Minoxidil: Apply to a dry scalp twice daily; maximum of 2 ml per day; avoid heat sources and cover head for 1 hour post-application.
- Finasteride: Emphasize the potential for sexual dysfunction; ongoing treatment is needed for lasting results.
- Spironolactone: Monitor for side effects and contraindications, especially during pregnancy.
Case Study Discussion
- Assesses identifying the condition, determining potential causes, management strategies, and relevant counseling points.
