The main function of the birth control pill is to suppress some hormones that do not only affect the uterus but also other parts of the body as well. And one of those parts is hair - specifically, hair loss.

With so many birth control applications to use, the pill is the most widespread contraceptive used by many women around the world.

It is always wise to ask doctors about all possible side effects that can occur when you start the pill.

In case your family medical history has pattern hair loss, the doctor would probably recommend using other birth control methods that do not suppress your hormones.

How birth control pills work?

A birth control pill is a form of birth control that stops pregnancy by using hormones. Because it comes in pill form, people call it "the pill." The pill is taken by mouth by women once a day. 

These oral contraceptives stop ovulation, which is when an egg is released from the ovary. They also change the lining of the uterus and the mucus in the cervix in ways that make it harder for sperm to reach the uterus and fertilize an egg.

Can birth control cause hair loss?

Birth control pills can cause hair loss as it contains synthetically made progestin, a hormone that makes the resting period longer than it should be. People with a family history of pattern baldness should avoid taking hormonal birth control pills and should opt for non-hormonal birth control.

There are two different types of pills:

  • Combined Pill: this pill contains both estrogen and progestin
  • Mini Pill: this pill only contains artificial progestin

Progestin, or combined with estrogen, can prevent women from getting pregnant. Progestin work is to thicken the mucus in the cervix to enable the sperm to pass through to reach the egg. Meanwhile, estrogen blocks the egg to be released.

Because of their high androgenic activity, these pills have become a reason for hair fall.

What hormone in birth control causes hair loss?

Hair growth has 3 phases, anagen, catagen, and telogen. Anagen is where the hair grows from hair follicles and stays for 2 to 7 years. Catagen is the in-between growth stage where the hair stops growing. This can be for up to 10 to 20 days. Telogen is a resting phase where the hair does not grow and loses around 30 to 100 hairs per day. This shedding process can last for 100 days.

Almost all birth control pills cause hair loss. These pills contain a hormone called Progestin. Progestin, if made synthetically, can create androgenic activity in the body. This can lead to imbalance hormones and cause hair loss. Androgens like DHT can make the Telogen phase (resting phase) stay for a long period which eventually causes hair fall.

How does birth control pill cause hair loss?

Most pills contain progestin as one of the components. This component is the main reason for hair loss.

Because progestin is an artificial hormone, it acts like an androgenic, which is a similar hormone to men. Because of progestin, there can be severe side effects to the body, and hair loss is one of them.

Women who are sensitive to any changes in the hormone, tend to experience hair loss by taking these birth control pills.

People with a family history of hair loss should not take birth pills as it might instigate hair loss in them as well. Therefore, there are few non-hormonal birth control ways that one can have, without the risk of losing their hair.

Once you take the birth control pills, your hair growing phase will go into the resting stage sooner than expected or the resting phase stays for too long. This phase produces thin and weak here which fall out immediately. This can lead to baldness as well.

Moreover, if hair loss is genetic in your family, taking birth pills will increase the chances of hair loss.

Hormonal birth control creates androgenic activity in the body which can worsen hair loss in women. Even if injecting hormones, getting skin patches, progestin implants or even vaginal rings can cause the process of hair loss to exacerbate.

If you already have high levels of androgens in your body, which is common in PCOD and PCOS, taking the right pill can not only treat hair loss but also help with female pattern baldness by making your body produce more oestrogen.
