Five essential hair care tips every woman over 40 should know

Hormones change, life gets busier, and your hair has a mind of its own—but that doesn’t mean it has to lose its strength, shine, or style. Whether it’s the beginning of perimenopause or the aftermath of decades of styling, colouring, and exposure to environmental stressors, your mane may not behave the way it used to. But that doesn’t mean great hair days are behind you. In fact, with a few smart tweaks and some TLC, your hair can look better than ever.

Hydration is non-negotiable

As oestrogen levels begin to drop in your 40s, so does your scalp’s natural oil production. Look for shampoos and conditioners rich in hydrating ingredients like hyaluronic acid, glycerin, aloe vera, and argan oil. Deep condition weekly and consider leaving a bit of conditioner in your hair post-wash if it feels particularly parched. Avoid sulfate based shampoos—they strip away natural oils that are already in short supply.

Scalp care = hair care

Healthy hair starts at the root, and yet, scalp care remains one of the most overlooked aspects of post-40 hair maintenance. Exfoliate your scalp once a week using either a gentle scrub or a scalp brush during your shampoo. Use lightweight, non-clogging oils like jojoba or rosemary oil to nourish and stimulate blood circulation. 

Handle with care—literally

Your hair becomes more fragile as you age. Years of heat styling, dye jobs, and environmental exposure weaken the cuticle, making strands more prone to breakage. Switch to microfibre towels or a soft cotton T-shirt to dry your hair. Avoid aggressive brushing when wet, and opt for wide-toothed combs. Limit heat styling and always use a heat protectant spray when you do. Invest in a silk pillowcase—it reduces friction and helps your hair retain moisture overnight.

Don’t fear the grey

Whether you’re embracing the silver or covering it up, your approach to colour should evolve with your hair’s changing texture and porosity. If you colour your hair, switch to ammonia-free or semi-permanent dyes that are less damaging. For natural greys, use purple shampoos to neutralise any yellow undertones and add shine. Try gloss treatments—they’re non-invasive and add vibrancy to both coloured and grey hair.

Nourish from within

Your hair reflects your internal health. Nutrient deficiencies can accelerate thinning, dryness, and dullness—especially post-40 when absorption slows down and hormonal shifts impact growth cycles. Make sure you’re getting enough biotin, omega-3 fatty acids, iron, vitamin D, and protein. If needed, consider supplements designed specifically for hair health. Drink more water than you think you need. Hair loss can also be a sign of thyroid imbalances or stress-related conditions—don’t hesitate to consult a doctor if you notice sudden or excessive shedding.
