Trichology Fundamentals

A lecture on trichology fundamentals: hair and scalp structure, distinguishing telogen effluvium from androgenetic alopecia, the hair growth cycle, and trichoscopy camera imagery.

About the course

Trichology Fundamentals is a lecture by Magdalena Koc on what happens in the scalp and hair follicle before a hairdresser even picks up the scissors. The course organizes hair structure, scalp structure, types of hair loss, and the hair growth cycle - the knowledge that underpins every trichology-related decision behind the chair.

The starting point is dividing the hair into a living part and a dead part. From there, the course moves through the arrector pili muscle, sebaceous glands, the hair matrix and papilla, the five layers of the epidermis, and the network of blood vessels you stimulate with every massage at the basin. The second part is about recognition: telogen effluvium and androgenetic alopecia, how to tell them apart during a consultation, alopecia areata, anagen effluvium and trichotillomania, plus scarring alopecia, after which hair no longer grows back.

In this course, you'll see

  • How hair is structured from the matrix and papilla to the cuticle scales, and why hair is the last part of the body to receive nutrients
  • Where scalp pain after a full day in a tightly pulled hairstyle comes from, and the role the arrector pili muscle plays in it
  • Why minoxidil lotion only works while you're using it, and what happens once you stop
  • How to distinguish telogen effluvium from androgenetic alopecia in a consultation, based on a single question about the amount of hair shedding
  • What hair follicle miniaturization and shaft heterogeneity are - why a client feels a thinner ponytail even with the same number of hairs
  • Which types of hair loss leave a scar, and why new hair won't grow back there
  • What black, yellow, and white dots at follicle openings mean, plus flame hairs, exclamation-mark hairs, and pigtail hairs
  • How the hair growth cycle works and what actually extends the anagen phase

This course gives hairdressers the language and the criteria they need. By the end, you'll be able to tell when a scalp condition is physiological, when it calls for trichological stimulation, and when a client needs to be referred to a doctor. Together with Trichology Consultation and Trichology in Practice, it forms a complete set: theory, the consultation process, and salon habits.

What you will learn

  1. 01How to distinguish telogen effluvium from androgenetic alopecia right from the client consultation.
  2. 02How hair is structured, and why nutrients reach it last.
  3. 03What hair follicle miniaturization is and how to spot it.
  4. 04Which types of hair loss leave a scar, and when to refer a client to a doctor.
  5. 05What black, yellow, and white dots at follicle openings mean.
  6. 06How the hair growth cycle works and what actually extends the anagen phase.

What's inside

Full access with the course
  1. Trichology Fundamentals - Hair splits into a living and a dead part1:50

    01Hair splits into a living and a dead part

    Everything that happens above the skin's surface is the shaft - and that's the dead part of the hair.

  2. Trichology Fundamentals - Where scalp pain comes from3:09

    02Where scalp pain comes from

    Very often that arrector pili muscle gets pulled in a completely different direction, and at that point it's simply strained.

  3. Trichology Fundamentals - Hair is nourished last5:55

    03Hair is nourished last

    Hair is treated as a vestigial organ, so if it's going to get anything, it's only at the very end.

  4. Trichology Fundamentals - What happens after you stop using minoxidil8:27

    04What happens after you stop using minoxidil

    Unfortunately, a large portion of the hair that managed to grow starts falling out.

  5. Trichology Fundamentals - You only see one of the five layers11:16

    05You only see one of the five layers

    The stratum corneum is just one of the five layers of the epidermis.

  6. Trichology Fundamentals - How deep a massage really reaches16:09

    06How deep a massage really reaches

    Your stimulation reaches all the way down to the muscle.

  7. Trichology Fundamentals - One question that separates two types of hair loss18:05

    07One question that separates two types of hair loss

    When a client tells you they're pulling out huge amounts of hair, that's telogen effluvium.

  8. Trichology Fundamentals - Hair follicle miniaturization19:23

    08Hair follicle miniaturization

    What happens is a phenomenon called hair follicle miniaturization.

  9. Trichology Fundamentals - A scar means the end of the follicle28:31

    09A scar means the end of the follicle

    Wherever a scar forms, there's absolutely no way for a follicle to miraculously regenerate there.

  10. Trichology Fundamentals - What you must never promise with psoriasis31:48

    10What you must never promise with psoriasis

    Psoriasis is an autoimmune condition, so we absolutely never promise anyone a cure for it.

  11. Trichology Fundamentals - Flame hair and trichotillomania38:18

    11Flame hair and trichotillomania

    Because the camera doesn't lie.

  12. Trichology Fundamentals - How many hairs a blonde has versus a redhead39:20

    12How many hairs a blonde has versus a redhead

    People with light hair - blondes - have the most hair, around 120,000 strands.

  13. Trichology Fundamentals - What trichological work actually involves43:21

    13What trichological work actually involves

    All of this contributes to extending the anagen phase.

  14. Trichology Fundamentals - Trichosiderin is not a melanin45:16

    14Trichosiderin is not a melanin

    If anyone tells you there's such a thing as trichosiderin, that is absolutely not a natural hair melanin.

FAQ

Is this course suitable for hairdressers with no trichology background?
Yes. This is an introductory course that organizes hair and scalp structure along with the basic types of hair loss. The educator moves from anatomy to recognition, so no prior background is needed.
How does this course differ from Magdalena Koc's other two courses?
This course is theory: structure, types of hair loss, and the hair growth cycle. Trichology Consultation walks through an entire client visit, while Trichology in Practice covers 25 points to apply in day-to-day salon work. The three courses complement each other and can be watched in any order.
Do you need a trichoscopy camera to take this course?
No. The camera comes up when discussing scalp images, but distinguishing telogen effluvium from androgenetic alopecia relies mainly on consultation and observation.
Does the course teach how to interpret blood tests and choose supplements?
Not to that extent. The educator explains why deficiencies show up in the hair, using low ferritin as an example, but analyzing blood tests and treatment protocols is covered in in-person courses.
Can a hairdresser work with scarring alopecia?
No. The course draws a clear line here: where a scar has formed, the follicle will never produce hair again, and diagnosis and treatment are a doctor's job. A hairdresser's role is to spot the problem and refer the client onward.
How long is the course?
The course runs 55 minutes and is divided into chapters, so you can revisit a specific topic - such as types of hair loss or the hair growth cycle - without watching the whole thing again.
