What Works – And Doesn’t – For Hair Loss?

October 27, 2025

Key Takeaways Copied to clipboard!

  • Hair loss affects up to half of all women, and the type of hair loss dictates the effective scientific treatment, making a formal diagnosis crucial. 
  • While stress or temporary events like COVID can cause shedding, persistent hair loss is often pattern hair loss (androgenetic alopecia) or autoimmune conditions like alopecia areata, which require different approaches. 
  • Social media presents a mixed bag for hair loss sufferers, offering both misinformation and community support, while access to specialized dermatological care can be difficult, leading some to telehealth options.

  • Key Takeaway: Hair loss, often perceived as a male issue, affects half of all women and can be emotionally devastating.
  • Summary: Pharmaceuticals correspondent Sidney Lupkin hosts the Short Wave episode focusing on hair loss. An anecdote illustrates the personal impact, noting that while not life-threatening, hair loss can feel like an identity slipping away. The episode aims to discuss causes and science-based treatments.
Hair Growth Cycles Explained

  • Key Takeaway: Normal hair shedding occurs at the end of the telogen (rest) phase when a new hair pushes the old one out, and this process is usually asynchronous across the scalp.
  • Summary: Each hair goes through cycles of growth, transition, and rest (telogen). Shedding happens when the rest phase ends and a new hair pushes the old one out. Stress, such as from COVID, can cause these cycles to synchronize, leading to temporary, larger sheds.
Types of Hair Loss

  • Key Takeaway: Pattern hair loss (androgenetic alopecia) typically presents as a widening part in women, while other types like alopecia areata or scarring alopecias have distinct symptoms like smooth spots, itching, or tenderness.
  • Summary: Most persistent hair loss is pattern hair loss, which is hormonal in women. Scarring alopecias often present with accompanying symptoms like scalp itching, redness, or pimples, signaling something beyond typical pattern loss. A formal diagnosis is necessary because different types respond to different treatments.
Diagnosis Challenges and Telehealth

(00:08:17)
  • Key Takeaway: Obtaining a formal diagnosis for hair loss can be difficult due to dismissive primary care doctors and long waits for dermatologists, prompting the rise of telehealth solutions.
  • Summary: Telehealth companies are stepping in to fill gaps by offering online consultations and mailed prescriptions, particularly for hormonal female pattern hair loss. However, experts caution that telehealth alone might miss diagnoses for look-alike conditions, such as fungal infections, which require in-person assessment.
Treatment Options Overview

  • Key Takeaway: Topical minoxidil (Rogaine) works by lengthening the hair’s growth phase, but newer prescription drugs like JAK inhibitors are showing promise for autoimmune hair loss (alopecia areata).
  • Summary: Minoxidil has been available for decades, working to keep more hair on the head, but can be messy and is restricted during pregnancy. JAK inhibitors, approved recently, target the overactive immune system in alopecia areata patients, showing significant regrowth in studies. Off-label treatments like oral minoxidil and spironolactone are also used for pattern hair loss under close medical monitoring.
