I am sorry to hear that your symptoms have worsened this year.
Firstly, hirsutism in young females is not an uncommon symptom, especially if you have polycystic ovarian syndrome (PCOS) . PCOS is one of the most common causes of hirsutism in young females like yourself.
Even though your periods are regular and you do not have acne, it does not necessarily mean you definitely do not have PCOS and that your excessive hair growth is definitely idiopathic.
I would recommend that you seek a doctor's opinion first to have a work up done for your hirsutism, after which we can then look into effective ways we can help you treat it.
Hirsutism in young girls is usually caused by excessive male hormones in the body, which hence leads to such symptoms. An effective way of controlling this would be via certain birth control pills such as Diane-35, which can effectively control the levels of male hormones and improve your hirsutism.
In addition to that, you can also complement the treatment with hair removal methods such as IPL or laser hair removal.
Ultimately, it is most important for you to seek treatment with a doctor that's experienced in treating young girls like yourself.
Hope this addresses your concerns!
Regards,
Dr Michelle Chia
