How to choose a shampoo: look at your scalp, not your hair
21.08.2026
People choose a shampoo by their hair — and almost always get it wrong. Shampoo washes the scalp, not the length: on the length it spends a few seconds while it runs off. So the first question is not «what is my hair like» but «what is my scalp like».
Working out your type in a day
Wash your hair and put nothing on the roots. Look again the next day:
- shine at the roots, hair sticking together in strands — an oily scalp;
- tight skin, fine dry flakes, itching — dry;
- fresh roots but dry ends — a normal scalp with damaged length, which is very common;
- redness and stinging from many products — sensitive.
An oily scalp
There is one mistake here: washing harder and more often. The skin answers by making even more oil. What you want is a gentle shampoo you could use every day:
Put it on the roots only, not down the length — the ends do not need it.
Dry and sensitive
Here the opposite works: less often, gentler, with warm water. Look for a shampoo without harsh detergents and marked for sensitive skin. If the flaking does not clear up for months, the shampoo may no longer be the problem — that is a question for a doctor.
Normal roots, dry ends
The most common case of all. Keep the shampoo neutral and mild and hand the length over to a conditioner — a wash and its matching conditioner are made for exactly that:
Three rules that hold for everyone
- Wash twice: the first pass takes off dust and styling, the second actually washes the scalp.
- Massage with your fingertips, not your nails, for 30–60 seconds.
- Rinse for longer than feels necessary — shampoo left behind is a common cause of itching.
One last thing: scalp type changes with the season and with age. If a shampoo worked for a year and does not now, it is probably you that changed, not the bottle.
