The Best Hair Care Routine for Thinning Hair After 40

The Basics: What to Stop Doing

Before building a positive hair care routine, it's worth addressing the common practices that can worsen thinning hair. Tight hairstyles (ponytails, braids, buns) that create tension on the scalp can cause traction alopecia — a form of hair loss caused by mechanical stress on follicles. Heat styling with high temperatures damages the hair shaft and can cause breakage that mimics hair loss. Aggressive brushing and towel-drying create friction that breaks fragile hairs. Chemical treatments (bleaching, perming, relaxing) weaken the hair shaft and increase breakage.

Shampoo and Conditioning

Choose a gentle, sulfate-free shampoo formulated for fine or thinning hair. Sulfates are effective cleansers but can strip natural oils and cause scalp irritation in some women. Look for shampoos containing ingredients like biotin (which works best when combined with oral biotin supplementation), caffeine (which has been shown in some studies to stimulate hair follicle activity), or ketoconazole (if scalp inflammation is a concern).

Apply conditioner from mid-shaft to ends only — avoiding the scalp prevents buildup that can weigh hair down and clog follicles. A lightweight leave-in conditioner can add volume and manageability without heaviness. For best results, combine your hair care routine with our comprehensive hair protocols that support hair health from the inside out.

Styling for Volume

Volumizing mousses and sprays can create the appearance of fuller hair. Apply to roots before blow-drying and use a round brush to lift at the roots. Dry shampoo can add texture and volume between washes. Consider a shorter cut — many women find that a well-cut bob or layered style creates more visual volume than long, heavy hair that accentuates thinning.
