9 expert-approved hacks for your healthiest-looking hair yet

We asked dermatologists, trichologists and leading stylists for the simple, science-backed tweaks that make the most visible difference to hair health. These are not miracle cures but practical, repeatable habits — from scalp-first thinking to styling choices — that boost shine, reduce breakage and help hair look its healthiest across textures and lengths.

Start with the scalp: the foundation of healthy hair

Healthy hair begins at the scalp. Experts emphasise gentle turnover of oils and avoidance of chronic irritation. That means choosing a shampoo frequency that matches your scalp’s sebum production, using a gentle, pH-balanced cleanser and incorporating a targeted scalp treatment if you experience dandruff, itch or persistent oiliness. Massaging the scalp for a few minutes during washing increases circulation and helps distribute natural oils without over-stripping.

Wash smarter — not necessarily less

How you wash matters more than how often for many people. Use lukewarm water to avoid raising the hair cuticle excessively, which can lead to frizz and dullness. Concentrate shampoo on the scalp and apply conditioner primarily to mid-lengths and ends. Leave-in conditioners and lightweight serums can protect hair between washes and reduce friction from styling.

Nine expert-approved hair hacks

• Scalp-first routine: gently exfoliate the scalp once a fortnight to remove product build-up and encourage healthy follicles.
• Pre-shampoo oiling: apply a light oil to very dry ends before washing to reduce water absorption and breakage.
• Use a wide-tooth comb on wet hair to detangle and avoid aggressive brushing that leads to split ends.
• Switch to silk or satin pillowcases to reduce friction-induced breakage and preserve hairstyles overnight.
• Limit heat: when using hot tools, apply a thermal protectant and keep temperatures below 180°C for fine hair, 200°C for thicker hair.
• Trim regularly: small, frequent trims every 8–12 weeks prevent splits from travelling up the shaft.
• Targeted strengthening: introduce a weekly protein mask if your hair feels limp or over-processed, alternating with moisturising treatments.
• Avoid heavy product layering: apply styling products sparingly and focus on one or two multipurpose items rather than numerous finishes that can weigh hair down.
• Sun and chlorine protection: wear a hat, use UV-protective products and rinse hair after swimming to minimise damage and colour fade.

These steps can be tailored — for instance, curly hair benefits more from leave-in moisturisers and less frequent shampooing, while very fine hair may prefer lightweight formulations and clarifying washes to avoid build-up.

How to implement changes without overhauling your routine

Introduce one or two hacks at a time and give them four to six weeks. Track changes in manageability, shine and breakage rather than expecting dramatic shifts overnight. Keep a basic ‘repair vs. moisture’ checklist: if hair snaps easily, it likely needs protein; if it stretches without snapping but looks dry, reach for moisturising agents.

Key Takeaways

• Scalp health is central — treat it gently and consistently.
• Washing technique and water temperature affect shine and frizz more than frequency alone.
• Protect from heat and environmental damage with targeted products and sensible styling temperatures.
• Introduce one change at a time and allow weeks to assess benefit.
• Tailor protein and moisture treatments to your hair’s current condition, not just its type.

Frequently Asked Questions

Q: How often should I shampoo if my hair feels greasy daily?

A: If oiliness builds daily, aim for a gentle shampoo every other day and use a dry shampoo between washes to absorb excess sebum. Very frequent harsh cleansing can paradoxically increase oil production, so choose pH-balanced formulas.

Q: Are leave-in conditioners necessary for all hair types?

A: Not always. Leave-in products are valuable for adding manageability and heat protection, especially in drier or chemically-treated hair. Fine hair can use lightweight serums or sprays; those with thick or curly textures often benefit from richer creams.

Q: Can I repair split ends without cutting them?

A: Split ends can’t be permanently repaired; trims are the only reliable solution. Temporary smoothing products and bonding treatments can reduce the appearance and delay the need for a cut.

Q: How do I know if I need a protein treatment?

A: Hair that feels overly stretchy when wet and snaps easily typically lacks protein. Introduce a protein mask cautiously — once every 3–4 weeks — and alternate with moisturising treatments to avoid brittleness.

Q: Is brushing more helpful or harmful?

A: Brushing can distribute oils and detangle when done correctly. Use a wide-tooth comb or a brush designed for your hair type, avoid vigorous brushing when wet, and work from ends to roots to prevent breakage.
