Sometimes the change happens gradually, over several years. Even though the hair care products stay the same, the condition of the hair can begin to change because of processes inside the body.<\/span><\/p><p><span style=\"font-weight: 400;\">Most often this is linked to hormonal changes, a lack of nutrients, stress and the body\u2019s natural ageing processes.<\/span><\/p><p><span style=\"font-weight: 400;\">In this article we look at why hair loss becomes more common after 40 and which solutions can help support stronger, healthier-looking hair.<\/span><\/p><p> <\/p><h2><span style=\"font-weight: 400;\">How does the hair growth cycle change?<\/span><\/h2><p><span style=\"font-weight: 400;\">Every hair goes through several phases:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the growth phase (anagen);<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the transitional phase (catagen);<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the resting and shedding phase (telogen).<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">In a healthy body most hairs are in the growth phase. Oestrogens help to extend this phase, which is why hair looks thicker and stronger.<\/span><\/p><p><span style=\"font-weight: 400;\">During perimenopause oestrogen levels fall, and as a result:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the hair growth phase becomes shorter;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">more hairs move into the shedding phase;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">hair becomes thinner and weaker.<\/span><\/li><\/ul><p> <\/p><h2><span style=\"font-weight: 400;\">DHT and follicle miniaturisation: a process that often goes unnoticed<\/span><\/h2><p><span style=\"font-weight: 400;\">One of the most common causes of thinning hair after 40 is increased sensitivity to DHT (dihydrotestosterone).<\/span><\/p><p><span style=\"font-weight: 400;\">DHT is formed from testosterone by the enzyme 5-alpha-reductase. When hair follicles become more sensitive to the effect of this hormone, what is known as follicle miniaturisation begins.<\/span><\/p><p><span style=\"font-weight: 400;\">This means that:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">hair gradually becomes thinner;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">its growth phase becomes shorter;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">hair density decreases;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">over time the follicles produce weaker hairs.<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">It is important to understand that the problem is usually not \u201ctoo many hormones\u201d. More often it is increased sensitivity of the follicles to the hormonal changes that happen naturally during perimenopause.<\/span><\/p><p><span style=\"font-weight: 400;\">This is exactly why women may notice more pronounced thinning even when their blood test results are normal.<\/span><\/p><p> <\/p><h2><span style=\"font-weight: 400;\">Other factors that can make hair loss worse<\/span><\/h2><p><span style=\"font-weight: 400;\">Hormonal changes often act together with other factors:<\/span><\/p><h3><span style=\"font-weight: 400;\">A lack of trace elements<\/span><\/h3><p><span style=\"font-weight: 400;\">A shortage of iron, zinc, selenium or biotin can weaken the hair follicles.<\/span><\/p><h3><span style=\"font-weight: 400;\">Stress<\/span><\/h3><p><span style=\"font-weight: 400;\">Raised cortisol levels can shorten the hair growth phase and encourage shedding.<\/span><\/p><h3><span style=\"font-weight: 400;\">A lack of protein<\/span><\/h3><p><span style=\"font-weight: 400;\">Hair is mostly made of keratin, so not getting enough protein in your diet can affect its strength.<\/span><\/p><h3><span style=\"font-weight: 400;\">Thyroid disorders<\/span><\/h3><p><span style=\"font-weight: 400;\">Changes in thyroid hormones are often linked to thinning hair in women after 40.<\/span><\/p><h3><span style=\"font-weight: 400;\">Glucose fluctuations<\/span><\/h3><p><span style=\"font-weight: 400;\">Raised insulin levels can drive hormonal processes that affect the condition of the hair.<\/span><\/p><p> <\/p><h2><span style=\"font-weight: 400;\">Which substances matter to hair follicles?<\/span><\/h2><p><span style=\"font-weight: 400;\">After 40, what matters to your hair is not only the shine on the outside but also what happens inside the follicle.
