The Science of Healthy Hair, Hair Loss and How to Regrow Hair | Huberman Lab Podcast

Dive deep into the biology of hair growth, the causes of hair loss and scientifically-backed methods to slow down the process or even stimulate hair regrowth.

Hosted by Andrew Huberman, this episode will dispel common myths about hair loss and explore various treatments like minoxidil, tadalafil, PRP, microneedling, Botox, and ketoconazole.

Impact of Hair Loss on Mental Health

Hair loss can lead to significant psychological distress and anxiety.

Therefore, understanding the biology of hair growth is crucial for implementing effective treatments.

Effect of Age and Genetics on Hair Loss

Age and genetics significantly impact hair loss.

With age, there is an increase in 5-alpha reductase activity, which converts more testosterone to dihydrotestosterone (DHT), leading to hair loss.

The Role of Androgen Receptors in Hair Growth

Androgen receptors on the scalp and face play a key role in hair growth.

Individuals with a high density of these receptors can grow thicker beards as DHT levels increase.

Topical Application of Caffeine for Hair Loss

Topical application of caffeine can stimulate hair growth by inhibiting phosphodiesterase.

However, it should be applied directly to the scalp as oral ingestion does not deliver sufficient concentrations.

What makes hair so very interesting from a biological standpoint is that every hair, every single individual strand of hair has its own little stem cell niche, meaning its own little pocket down there in the follicle in which specific stem cells give rise to those hairs for different durations of time. – Andrew Huberman

Benefits of Ketoconazole Shampoos

Ketoconazole shampoos with a 2% concentration can slow hair loss and combat dryness and brittleness.

They can be a part of a comprehensive hair loss treatment regimen.

Promising Results from Microneedling

Microneedling has shown promising results for hair growth.

It’s a mechanical approach that can be combined with chemical treatments for more effective results.

Combination treatments that involve a mechanical stimulus and a chemical stimulus are always going to be better than either one alone. – Andrew Huberman

Use of Finasteride for Hair Growth

Finasteride can increase hair count by up to 20% and reduce hair loss in 90% of users.

However, it should be used cautiously due to potential side effects.

Importance of Consulting a Health Professional

Individual responses to treatments vary widely.

It’s important to start with minimal effective dosages and monitor side effects.

Always consult with a healthcare professional before starting any treatment regimen.
