Hair loss, also known as alopecia, occurs when hair falls out faster than it grows back, or when hair follicles shrink and produce shorter, thinner strands over time. This can significantly affect a person's quality of life and confidence. But what causes it — and what options are available?
What Causes Hair Loss?
Hair loss can be triggered by a variety of factors, including:
- Hormonal changes (postpartum, menopause)
- Thyroid dysfunction
- Genetics and aging
- Autoimmune diseases
- Stress
- Certain medications
Identifying the root cause is the first step — because treatment is tailored to what's driving your hair loss.
Available Dosage Forms for Hair Loss Treatment
Compounded medications for hair loss can be prepared in several forms depending on your needs and preferences:
- Capsules
- Tablets
- Creams / Lotions
- Foams
- Solutions
For topical options, apply directly to the scalp — not to the hair itself — for best results.
Over-the-Counter Supplements That Can Help
Alongside prescription treatment, a pharmacist may recommend these supplements to support hair growth:
Fish Oil (Omega-3s)
Studies show that Omega-3s reduce inflammation and can help thicken and nourish hair. You can also get Omega-3s from foods like salmon, egg yolks, walnuts, hemp seeds, white fish, and tuna.
Zinc
Supports the hair follicle, inhibits follicle regression, and accelerates recovery.
B-Complex (especially B-5 and Biotin)
Biotin helps rebuild damaged hair. Vitamin B-5 (pantothenic acid) supports the adrenal gland, which regulates cortisol — our stress hormone.
Vitamin C
Fights oxidative stress, a contributor to hair loss and graying. As we age, free radicals increase while the body's antioxidant defenses decline — Vitamin C helps offset this.
Saw Palmetto
A plant extract that blocks DHT (dihydrotestosterone), a hormone linked to hair loss. Particularly beneficial for androgenic hair loss (male and female pattern baldness).
Ashwagandha
An adaptogenic herb that helps the body manage stress and balance cortisol levels — making it a useful option for stress-related hair loss.
Collagen
A vital protein for hair strength and structure. As collagen production declines with age, supplementing can increase the amino acids needed to build hair proteins and reinforce follicles.
Prescription Medication Options
Depending on the cause of your hair loss, a custom formulation may be compounded to address your specific concerns. Keep in mind: results typically take 2–3 months to appear, with maximum benefit seen within 6–12 months. Consistency is key.
Minoxidil
The active ingredient in Rogaine. It reactivates hair follicles, prolongs the growth cycle, and increases follicle activity. Available topically or orally.
Possible side effects: scalp irritation, itchiness, dryness (topical); increased body hair growth, lightheadedness, headaches (oral).
Naltrexone
An excellent option for hair loss related to autoimmune conditions. It works by reducing inflammation and can be taken orally or applied topically.
Possible side effects: headaches, vivid dreams (oral); skin irritation, dryness, redness (topical). Generally well tolerated.
Finasteride & Dutasteride
These medications block 5-alpha reductase, preventing the conversion of testosterone to DHT — a key driver of pattern baldness. Best used topically for hair loss.
Possible side effects: changes in libido, scalp flakiness or dryness.
Important: Women of childbearing age should not use or come into contact with these medications due to the risk of birth defects.
Spironolactone
Has an anti-androgen effect that slows androgen production and prevents follicle miniaturization. A good option for pattern baldness. Available topically or orally.
Possible side effects: lightheadedness, dizziness, increased sun sensitivity. Note: the topical form has an odor — discuss with your provider to find the right fit.
Tretinoin
Increases cell turnover, improves blood flow to follicles, and prolongs the hair growth phase. Patients typically start at a lower dose and titrate up over time.
Possible side effects: skin irritation, peeling, redness, dryness.
