The Hair Loss Foundations

Skin anatomy, the three layers, scalp glands, and why the follicular environment matters more than the products on top of it

Hair biology — the shaft, the follicle, terminal vs. vellus hair, and what miniaturization actually looks like at the cellular level

The hair growth cycle — anagen through kenogen — and why every treatment mechanism connects back to it

Keratin chemistry, amino acids, hair texture classification, and the real science behind scalp pH (vs. what's just marketing)

Every major type of alopecia — androgenetic, areata, telogen effluvium, traction, cicatricial, hormonal — with patterns, mechanisms, and when to refer out

Scalp conditions — dry scalp vs. dandruff vs. seb derm vs. psoriasis — how to tell them apart and what each one means for the follicle

The internal picture — hormones, the androgen pathway, nutritional deficiencies, chronic stress, and how internal drivers show up as patterns you can learn to read

The scalp microbiome, why scoping changes your clinical practice, how to hold the emotional conversation, and treatment fundamentals — what works, what doesn't, and why

You're a hairdresser or esthetician and you're tired of guessing when a client asks why their hair is falling out

You've paid for hair loss education before and it turned out to be a glorified product catalog

You're considering trichology and want the actual science before committing to clinical training

You want a clinical reference guide — with real mechanisms, not scripts — that you'll come back to between clients
