Haircare Basics: Building a Simple Hair Routine

Haircare works best when you separate two things people usually treat as one: the scalp and the lengths. The scalp is living skin that produces oil, sweats and needs cleansing. The lengths are dead keratin fibres that need conditioning and protection from everything you do to them. Most routines improve noticeably once you start treating those two things differently.

A simple weekly structure

That is the whole routine. Everything else — scalp scrubs, bond builders, oils, serums — is optional and should be added because you have identified a specific problem, not because a routine looks more thorough with more steps.

Technique that makes a difference

• Focus shampoo on the scalp and let the runoff cleanse the lengths.
• Apply conditioner from mid-length to ends, avoiding the scalp unless the product is designed for it.
• Use a wide-tooth comb on conditioned, wet hair rather than brushing dry tangles.
• Rinse with lukewarm water; very hot water can leave both scalp and lengths feeling dry.
• Pat hair with a towel or use a microfibre wrap rather than rubbing vigorously.
• Finish with a cooler rinse if you can tolerate it — it helps the cuticle lie flatter.

Choosing a wash frequency

There is no correct number of washes per week, and the advice to wash less often is not universal. An oily scalp left unwashed can become itchy and flaky; dry, curly hair washed daily can become brittle. The useful approach is to experiment in one direction for two weeks and notice two things: how your scalp feels on day two, and how your lengths feel on wash day.

Most people land somewhere between two and four washes a week. If you exercise daily or use a lot of styling product, you may need more frequent cleansing — and a gentle, sulphate-free shampoo used often is usually kinder than a harsh one used rarely.

Managing heat styling

• Dry hair to around 80% before using a straightener or curling iron.
• Use the lowest heat setting that achieves the result you want.
• Apply a heat protectant evenly through damp or dry hair before styling.
• Use a diffuser on curly hair to preserve curl pattern and reduce frizz.
• Finish with the cool-shot button to help set the style.
• Take at least two or three heat-free days a week if your hair allows it.

Heat damage is cumulative and permanent for the hair that has already been damaged — you cannot repair it, only grow it out and protect what comes after. That is the single strongest argument for spending money on a good dryer with real heat settings rather than on another treatment product.

Adapting to your hair type

• Fine hair: lightweight conditioner on the ends only, minimal product, regular trims to keep density looking full.
• Thick or coarse hair: richer conditioners and masks, more time on detangling, and sectioning when you style.
• Curly or coily hair: cleanse less often, condition generously, style wet, and dry with a diffuser on low.
• Colour-treated hair: sulphate-free or colour-safe shampoo, cooler water, and a weekly mask.
• Oily scalp, dry ends: shampoo the scalp properly, condition only the lengths, and resist applying oils near the roots.

Scalp care basics

The scalp is skin, and it responds to the same principles as the skin on your face: cleanse it properly, do not irritate it, and do not smother it. Most scalp problems that bring people to a pharmacist are the result of either under-cleansing or over-treating.

• Shampoo the scalp, not just the hair — use fingertips, not nails.
• Rinse for longer than feels necessary; residue is a common cause of itchiness.
• If you use dry shampoo, clarify more often to prevent build-up.
• Avoid very hot water, which strips the scalp and can trigger rebound oiliness.
• Persistent flaking, soreness or patches should be assessed professionally rather than scrubbed harder.

Common haircare mistakes

• Applying conditioner to the scalp, then wondering why roots look flat.
• Brushing dry, tangled hair from the roots down instead of detangling wet hair from the ends up.
• Using heat tools on hair that is still wet, which is far more damaging than dry heat.
• Washing in very hot water because it feels cleaner.
• Switching products every fortnight and never giving one a fair trial.
• Tying hair back tightly in the same place every day, which causes mechanical breakage over time.

Building the routine on a budget

A good hair routine does not require expensive products, and the areas where spending helps are narrower than marketing suggests. A well-made dryer with real heat settings genuinely justifies its price because it protects your hair every time you use it. Shampoo and conditioner, by contrast, are rinse-off or short-contact products where mid-range formulas often perform as well as luxury ones. If you have a limited budget, put it towards the tool and a weekly mask, and keep the everyday wash simple.

Give any new routine a month before judging it. Hair changes slowly, and the most common mistake is switching products every fortnight and never giving any of them long enough to show what they can do.
