Short on time? Read our one-minute summary and get all the facts:
- Researchers have identified a key protein, MCL-1, that protects hair follicle stem cells and is crucial for new hair growth.
- Scientists found that turning off MCL-1 in mice led to hair loss and bald patches that wouldn’t regrow, revealing its vital role in hair regeneration.
- Experts say this could give scientists a proven target for developing future baldness therapies.
- Delivering MCL-1 directly to human hair follicles is tricky, but boosting it through other proteins could be a promising workaround.
- While treatments are still years away, this research paves the way for new strategies to prevent or reverse hair loss.
