The Alopecia Help Collection

If you have recently been told that you have androgenetic alopecia, you may be wondering why this has happened now - and whether menopause or testosterone is to blame. Female pattern hair loss becomes much more common after menopause, but the explanation is more complex than simply having “too much testosterone”.

Most of us think of prolactin as the hormone responsible for milk production after childbirth. It hardly seems relevant to hair. So I was surprised to discover that human hair follicles don’t just respond to prolactin. They appear to make it themselves. That immediately raises a question. Why would a hair follicle produce a hormone best known for helping mothers breastfeed? The answer isn’t obvious. In fact, despite more than twenty years of research, scientists still don’t k

Does melatonin do more than help us sleep? Hair follicles produce their own melatonin, yet scientists are only beginning to understand why. A fascinating new laboratory study suggests melatonin may influence the stem cells responsible for growing new hair, adding another piece to the complex puzzle of androgenetic alopecia.

One treatment kept standing As I reached the end of the paper, one treatment kept surviving. Low-level laser therapy. It isn’t the most powerful treatment we have for hair loss. But it is drug-free. It is non-invasive. And it has one of the most reassuring safety profiles during pregnancy.

“The most important part of PRP happens long before the first injection.” “We specialise in PRP. But we don’t start with PRP. We start with you.”

Where Do You Keep Your Minoxidil? My latest bottle of freshly compounded 6% topical minoxidil arrived in the post this morning. I unpacked the little 30 mL bottle and left it at the bottom of the stairs, intending to take it upstairs later. Then I made myself a hot chocolate and sat down to read some newly published research papers. Within a few minutes, I’d got up and moved the bottle because of what I’d just read. I like to think I’m pretty careful with medicines. Tabl

One thing that struck me was how much of the discussion wasn’t really about eyebrows at all. It was about confidence. Before their transplants, many of the 30 described spending a lot of mental energy thinking about their eyebrows.

PRP wasn’t originally developed for hair loss. Discover how a treatment designed to support wound healing evolved into one of the most widely studied regenerative therapies for androgenetic alopecia.

Does Mounjaro cause hair loss? Dr Gwen Adey explores what the latest research actually shows, why rapid weight loss may be the real culprit, and what she would look for in clinic if a patient developed hair shedding while taking Mounjaro.

A new 2026 review explores how hair loss affects transgender women, including the role of hormone therapy, oral minoxidil, finasteride, hair transplantation and emerging approaches to hair restoration.

New research suggests PRP is far more complex than platelet count alone, with patient biology and inflammation also influencing outcomes.

New research suggests PCOS hair loss may involve insulin resistance and inflammation — not just hormones alone.

A 2026 study found stress, infections, low ferritin and vitamin D deficiency commonly linked to sudden hair shedding.

A major 2026 review found little evidence that biotin supplements help most hair loss sufferers unless true deficiency exists.

A 2024 ultrasound study found measurable scalp tissue changes beneath the surface in androgenetic alopecia.

Hair loss in women is multi-factor, not just hormonal. Treating one part alone often explains why many women don’t see results.

Hair loss is not just hormonal. The environment inside the hair follicle may change, becoming less stable and more inflamed.

2026 study found PRP improved hair transplant density by ~25% at 6 mont

Laser therapy may help reduce inflammation in scarring alopecia, but current evidence is limited and uncertain.

Hair loss exposes the scalp to more sun. Learn why this matters for skin cancer risk—and how simple protection can make a difference.
