Azelaic acid is a promising hair loss solution for men and women, offering anti-inflammatory, antimicrobial, and DHT-blocking benefits that support scalp health and regrowth. Studies show 5% azelaic acid can improve hair density and thickness, especially when combined with minoxidil 5%. Safe and well-tolerated, it’s available in prescription compounded formulas through providers like Anagen.
“Azelaic acid may improve scalp health, calm inflammation, and reduce local DHT activity, all of which can help protect and support hair follicles.” - Dr. Blake Bloxham, Chief Medical Officer at Anagen and Hair Transplantation Surgeon
Hair loss is a concern for both men and women, and while treatments like minoxidil 5% and finasteride are widely known, azelaic acid is emerging as a promising adjunct therapy for treating hair loss. With its anti-inflammatory, antimicrobial, and potential DHT-blocking properties, it offers benefits to both men and women.
At Anagen, we’re seeing growing patient interest in using azelaic acid in combination with 5% minoxidil to address thinning hair, scalp inflammation, and follicle health.
Azelaic acid is a naturally occurring dicarboxylic acid found in barley, rye, and wheat. Traditionally used in dermatology to treat acne, rosacea, and hyperpigmentation, it has well-documented anti-inflammatory and antimicrobial benefits. But beyond skincare, azelaic acid is now being explored as a hair loss treatment thanks to its ability to:
Soothe scalp inflammation → protecting follicles from chronic irritation.
Support scalp microbiome balance → creating healthier conditions for regrowth.
Block 5-alpha reductase locally → reducing DHT, the main hormone driving hair follicle miniaturization.
These benefits explain why azelaic acid is increasingly included in compounded hair loss solutions.
The question many ask is: how does azelaic acid work for hair? Research suggests it supports regrowth by targeting both the hormonal and inflammatory factors behind hair loss.
By inhibiting 5-alpha reductase, azelaic acid may lower scalp DHT, similar to finasteride but to a much lesser extent.
Its anti-inflammatory action calms scalp irritation that could otherwise accelerate hair loss.
Its antimicrobial properties prevent overgrowth of microbes like Malassezia, which can worsen scalp conditions linked to hair loss.
Azelaic acid isn’t FDA-approved as a standalone hair loss treatment, but evidence shows it can help:
A randomized study (Thanomkitti et al.) found that 5% azelaic acid improved hair density by 20.4% in 6 months.
Hair shaft diameter increased by 5.3%, comparable to improvements with 2% minoxidil.
Its dual benefits (DHT reduction + anti-inflammatory action) make it useful for both female pattern hair loss (FPHL) and male androgenetic alopecia.
At Anagen, we offer a compounded solution that combines 5% azelaic acid with 5% minoxidil in a once-daily topical.
Minoxidil 5%: Prolongs the anagen (growth) phase, boosts scalp circulation, and stimulates follicle activity.
Azelaic Acid 5%: Reduces local DHT, soothes inflammation, and supports scalp health.
This synergy makes it a very useful and particularly well tolerated hair loss treatment for both men and women.
Consistency is key for using azelaic acid effectively:
Step-by-step application:
Start with clean, slightly damp hair (post-shower is ideal).
Apply 1 mL of the topical to thinning or problem areas.
Gently massage into the scalp with clean fingertips.
Recommended dosage:
Concentration: 5% azelaic acid
Volume: 1 mL daily
Best use: Often combined with minoxidil 5% for enhanced results
Most users see improvements in 3–6 months when applied consistently.
Most tolerate azelaic acid well. Possible mild side effects include:
Scalp itching or tingling
Temporary redness
Dryness or flaking
These usually improve with continued use or slight adjustments to frequency.
Because drugstore products are too weak for regrowth, effective azelaic acid hair loss treatments come from:
Telehealth providers like Anagen (customized for men and women)
Compounding pharmacies preparing prescription-strength solutions
Dermatologist prescriptions for multi-ingredient formulas
Anagen sells a 5% Azelaic Acid 5% Minoxidil topical hair loss treatment.
What is azelaic acid used for in hair loss?
It helps block DHT locally, reduce inflammation, and support scalp health thus making it a valuable addition to regrowth formulas.
Is azelaic acid good for hair?
Yes, clinical studies show improved density and thickness, especially when combined with minoxidil.
Is azelaic acid a DHT blocker?
Yes, it may inhibit 5-alpha reductase in the scalp, reducing DHT formation but to a much lesser extent than drugs like finasteride or dutasteride.
Is azelaic acid as effective as finasteride?
No. While azelaic acid may mildly inhibit DHT, finasteride inhibits serum and scalp DHT by 60-70%. Azelaic acid may serve as a helpful adjunct therapy to those on finasteride.
Does azelaic acid increase keratin production?
Some studies suggest it may support keratinocyte function, but its main benefits are as an anti-microbial and anti-inflammatory agent.
Which acid is best for hair growth?
Azelaic acid shows strong promise, but others like tretinoin (retinoic acid) also play a role by improving absorption of growth agents.
What to avoid when using azelaic acid?
Avoid applying to broken or irritated skin, and limit combining with harsh scalp treatments that may cause extra dryness.
Azelaic acid is an emerging adjunct therapy for treating hair loss due to its anti-microbial, anti-inflammatory effects. As a hair loss solution for men and women, it’s most effective in compounded formulas especially when paired with 5% minoxidil.
