Fifty is the average age for menopause, but changes to your hair can begin long before, and is one reason why hair thinning during menopause is difficult to counteract. Nobody over 40 has the same volume of hair they had in their twenties, but menopause is an accelerating cause. The pattern of menopausal hair thinning is similar to the early stages of male pattern hair loss.
Ask your stylist. She might suggest a short cut, a different part, maybe a gentle body wave. Try a styling product for thin hair to hide bare spots. Apply it to the root area then gently blow dry to build volume. Let your hair air dry for a while before you use the dryer. Special cosmetics can disguise parts of your scalp that show. Think about keratin fiber hair cosmetics. Sprinkle them over the thinning patch. Their static charge makes hair look thicker.
