A step-by-step framework for a routine that fits your concern, your hair type and your budget, without buying more than you need.
How Many Products Does a Hair Routine Actually Need?
Four. A cleanser matched to how often you wash, a conditioner applied only to the lengths, one weekly treatment aimed at your main concern, and a leave-in for protection. Everything beyond those four is optimisation, not foundation, and most routines that fail do so because they add products instead of matching them.
- Cleanser: chosen for wash frequency first, concern second
- Conditioner: mid-lengths to ends only, never the roots
- Weekly treatment: bond builder, protein mask or scalp exfoliant depending on your concern
- Leave-in or protectant: non-negotiable if you use heat
How Do You Match a Routine to Your Hair Type?
Start from the concern that bothers you most, not from your hair type. Type determines how heavy a formula you can wear; concern determines what the weekly treatment should do. Fine hair with breakage needs a lightweight bond builder, while coily hair with breakage needs a rich one, same concern, opposite textures.
The most common routine mistake is treating hair type and hair concern as the same question. They set different variables: type sets the weight, concern sets the active.
Step 1: Name one concern
Damage, dryness, colour fade, flatness or scalp trouble. Pick the one you would fix first if you could only fix one. Our quiz does this in four questions if you would rather not decide alone.
Step 2: Set your wash rhythm
Daily washing demands the mildest cleanser you can find. Weekly washing allows a richer one and makes the treatment step more important. Most people sit at every two to three days.
Step 3: Add one treatment, not three
Give a single weekly treatment six weeks before judging it. Stacking a bond builder, a protein mask and a scalp scrub in the same week makes it impossible to know what worked.
What Should a Routine Cost?
A complete four-product routine runs from roughly €35 at drugstore level to over €150 at salon level, and the gap is smaller than the price suggests. The cleanser and the weekly treatment are where spending more tends to show; conditioner and leave-in perform similarly across price bands.
How Long Before You See Results?
Four to six weeks for a treatment to show measurable change, longer for scalp conditions. Hair grows about a centimetre a month, so anything below the mid-lengths is already-formed fibre, you can strengthen and seal it, but you cannot regrow it. Judge a routine on new growth and on how the lengths behave after washing, not on day-one shine.

Questions
Frequently asked
01 What is the minimum hair care routine?
A cleanser matched to your wash frequency, a conditioner on the lengths, one weekly treatment aimed at your main concern, and a leave-in if you use heat. Four products cover almost every case.
02 How long should you test a new routine?
Six weeks. Treatments need a full skin and growth cycle to show measurable change, and adding or swapping products in the meantime makes it impossible to know what worked.
03 Do expensive hair products work better?
Sometimes, and unevenly. Cleansers and weekly treatments tend to justify a higher price; conditioners and leave-ins perform similarly across price bands. Spend where the active does the work.
