Patient Medication Information: uses, side effects, how to take - Women's GLN-Minoxidil

What is Women’s GLN-MINOXIDIL used for?

  • Women’s GLN-MINOXIDIL is used for the treatment of female pattern hair loss/thinning in women aged 18 years of age and older. It prevents further hair loss and helps hair re-growth.

How does Women’s GLN-MINOXIDIL work?

Women’s GLN-MINOXIDIL contains minoxidil, which is thought to work by aiding the blood flow to hair follicles on your scalp and thereby helping hair re-growth. Initial hair re-growth may look soft, downy (“vellus” hair), and may be barely visible. After further treatment, hair re-growth may change and become the same colour and thickness as the rest of the hair.

Women’s GLN-MINOXIDIL is more effective if you are experiencing gradually thinning hair on the top of your scalp (as shown in the image below).

Minoxidil Foam

Gradual hair loss/thinning on the top of the scalp

Female Pattern Baldness or Hereditary Hair Loss is recognizable because:

  • Of the pattern of hair loss (see diagrams on the previous page).
  • Hair loss starts gradually and progresses.
  • other family members have experienced it.
  • No other symptoms are present with your hair loss.

    Non-female pattern hair loss

    Do not use if you have patchy hair loss as shown in the picture to the left.

Since normal hair growth takes time, hair regrowth with Women’s GLN-MINOXIDIL also takes time. Results may be seen as early as 3 months, but, for some women, it may take at least 6 months. If you do not see results in 6 months, stop using the product and see your doctor.

The amount of hair regrowth is different for each person. Not everyone will respond to Women’s GLN-MINOXIDIL. The response to this medicine cannot be predicted. No one will be able to grow back all of her hair.

You may respond better if you have been losing your hair for a shorter period of time (less than 10 years).
