Article: Minoxidil and Post Menopausal Hair Loss

Minoxidil and Post Menopausal Hair Loss

Minoxidil is a common medication prescribed for the management of male pattern hair loss.

Does it have a place in menopausal hair loss? Let's take a look. 

 

Why does hair texture change during menopause?

Oestrogen affects the hair growth cycle, the health of the scalp and also the health of hair follicles. Oestrogen is also responsible for the production of oils that keep the hair soft, smooth and lustrous. 

During menopause, oestrogen levels decline rapidly in comparison to testosterone. The imbalance of oestrogen and testosterone causes hair texture to change, increases hair shedding and also follicle miniaturisation (the hair follicles become smaller and the hairs that grow from the miniaturised hair follicles look finer).

Unlike male pattern hair loss, menopausal hair loss occurs mostly on the crown and there is a distinct widening of the midline. 

 

Is Minoxidil effective in menopausal hair loss?

A study published in 2019 on 369 women experiencing female pattern hair loss found 5% Minoxidil foam effectively regrows hair after 12 weeks of treatment, with postmenopausal women seeing the most improvement in nonvellus hair count compared to premenopausal women. 

For women not responding to topical minoxidil, low dose oral minoxidil have shown to be promising in many studies. There is also better adherence with low dose minoxidil (more convenient to use). The main limitation of using oral minoxidil are its possible side effects such as hypertrichosis (excessive body hair) and heart palpitations.

 

Can you combine Minoxidil with Ketoconazole for menopausal hair loss?

Ketoconazole 2% shampoo have shown in several clinical studies to help improve hair density and also reduce hair shedding in both male and female patter hair loss. There are no studies published on the effects of Ketoconazole specifically for menopausal women. Ketoconazole is thought to work by reducing androgen levels in the scalp and reducing scalp inflammation that can often lead to hair loss. Ketoconazole shampoo should be incorporated 2-3 times a week if appropriate. The limitation with Ketoconazole shampoo is excessive drying of the hair.
