Quick answer: See a hairdresser for how your hair looks: cuts, colour, styling and treatments for healthy hair. See a trichologist for why your hair or scalp is misbehaving: shedding, thinning, bald patches, breakage, or an itchy, flaky scalp that won't settle. At Tess Hair and Scalp Clinic on Botanic Avenue in Belfast, you get both under one roof.
Hairdressers are secretly therapists. Within ten minutes of sitting in the chair, most people have shared their relationship status, their boss's worst habits and their entire summer holiday itinerary.
So it's no surprise that your hairdresser is often the first person you tell about your hair loss. The question is whether they're the right person to fix it.
What does a hairdresser do?
A hairdresser is an expert in how your hair looks and behaves day to day. That covers:
cutting and styling
colour, highlights and toning
conditioning and smoothing treatments
extensions, braids and weaves
advice on products and routines for healthy hair
A good hairdresser is brilliant at making hair look its best. What they're not trained to do is work out why your hair is falling out, or treat a scalp condition. (Some will try. Bless them. Please don't let them.)
What does a trichologist do?
A trichologist is a hair and scalp specialist. The Institute of Trichologists describes the clinical side as the diagnosis and treatment of hair and scalp problems, and notes that trichologists are not medically qualified. Instead of asking "how should this look?", a trichologist asks "why is this happening?".
That means assessing shedding, thinning, bald patches, breakage and scalp problems, looking at your scalp under magnification, considering things like diet, stress, illness and blood test results, and building a treatment plan. If you need a doctor, a trichologist will tell you.
Trichologist vs hairdresser at a glance
A hairdresser asks "how should your hair look?". They're the right person for cuts, colour, styling, extensions and treatments for healthy hair. You leave with a new look.
A trichologist asks "why is your hair or scalp misbehaving?". They're the right person for shedding, thinning, bald patches, breakage and scalp problems. They look at your scalp, your follicles and the reasons behind the problem, and you leave with the likely cause and a plan.
Both double as therapists. One just has a scalp camera.
Can a hairdresser help with hair loss?
A hairdresser can help you live with hair loss while it's being treated, and that matters more than people think. A clever cut, the right colour, volumising styling, a topper or a hair system can make thinning hair look fuller straight away.
But a hairdresser can't tell you why it's happening or treat the cause. That's where a trichologist comes in. The best results usually come from both working together: one sorting the cause, the other sorting the look.
When your hairdresser should send you to a trichologist
Hairdressers often spot hair problems before you do, because they see the back of your head and you, mercifully, don't. Signs a good hairdresser will flag:
a round, smooth bald patch
a crown or parting that's thinner than last time
thinning edges from tight styles
a red, scaly, sore or unusually oily scalp
lots of short, broken hairs
much more hair coming out when they wash or brush it
If your hairdresser has gone quiet and started saying "hmm" at the back of your head, it's worth booking a hair and scalp analysis. The "hmm" is professional code. It means "I've seen something, I just don't want to ruin your holiday story."
Why having both under one roof helps
At Tess Hair and Scalp Clinic, the trichology clinic and the salon share the same building on Botanic Avenue. That means:
your trichology plan and your hairstyle can be planned together
braids, extensions and colour can be done with your scalp in mind
hair systems and toppers can be fitted and styled in the same place
you only have to tell your life story once
Should I see a hairdresser or a trichologist first?
If your hair is healthy and you want a change, see a hairdresser. If something has changed that you can't explain, like more shedding, thinner patches, snapping or an unhappy scalp, see a trichologist first. You can always get the fun haircut afterwards. You might even need it for the "after" photos.
Frequently asked questions
Is a trichologist better than a hairdresser for hair loss?
For finding out why hair loss is happening and treating the cause, yes. A hairdresser is the right person for cuts, colour and styling that make thinning hair look fuller.
Can a hairdresser diagnose hair loss?
No. A hairdresser can notice signs of hair loss, but working out the type and cause is the job of a trichologist or a doctor.
Do trichologists cut hair?
Most don't. At Tess Hair and Scalp Clinic, the trichology clinic and the hair salon are under one roof, so you can see both.
What is a hair loss salon?
Usually a salon that offers solutions for thinning hair, like toppers, hair systems, extensions and volumising cuts. It's most useful when it works alongside a trichologist who can treat the cause.
