Why do I lose more hair when I start my treatments?

It can be frustrating for people who start using hair loss treatments when they don’t see immediate results. What’s more frustrating is that you might lose more hair in the first few weeks of treatment, and this can be distressing. Here we look at the treatments available and explain what you should expect to see in that first month of use.

Is the hair loss caused by hair loss treatments?

First, let’s make sure the hair loss you are seeing is indeed in addition to what would normally be seen as natural hair loss, known as shedding. It’s important to remember you will lose hair naturally regardless of using the treatments. 

According to the NHS1 we can lose between 50 and 100 hairs over a 24 hour period, so if you do happen to spot any loose hairs it could just be part of our normal and healthy daily hair loss

However, there is no doubt that some additional hair loss can be seen when you first start using hair loss treatments.

Will I have initial hair loss when I start using Minoxidil?

Hair loss is a common occurrence within the first four weeks of treatment with a product like Minoxidil2 (also known as Regaine). But don’t worry. This is actually a good sign that the treatment is starting to work. This is because Minoxidil increases the speed of your hair growth cycle.

Minoxidil starts to reset the hair cycle for each follicle and pushes them into the ‘anagen’ (or growth) phase.3 This newly stimulated growth of stronger hair strands then pushes out the older

hairs that were in the ‘telogen’ or resting phase. These hairs would have fallen out anyway during this part of the cycle. It’s just that the process has been accelerated by the new growth.

Does Finasteride cause initial greater hair loss?

Finasteride, sometimes referred to by the brand name Propecia, is a pill that you take orally once a day. Like Minoxidil, Finasteride promotes the anagen phase of the hair growth cycle so you will see some initial hair loss.4

The key with Finasteride, is that you must continue to use the treatment otherwise your hair loss will return. Also, it doesn’t completely stop the effects of male pattern baldness, it just reduces them and slows them down.5 In other words, over a prolonged period you may still experience hair loss when using the treatment.

Should I expect to lose hair after a hair transplant?

Compared to other treatments, in terms of guaranteed results, hair transplants are largely successful. But you may still see some initial hair loss afterwards. Don’t worry as, like other treatments, this is part of the process.6 However, if you suffer from male pattern baldness, your transplanted hair follicles can still be at risk of eventually succumbing to the effects of this condition.

What should I do if I am still concerned?

It’s important to remember that your own experiences may differ from others. Ultimately, everyone is different and the way your hair responds to treatment may vary. At the same time, you need to be sure that hair loss treatments are the right option for you, which is where the Fagron TrichoTest™ can help. 

This unique and innovative test analyses your different gene variations and lifestyle factors, which is then compiled into a report explaining which treatments would work best for you. This information is then shared with a hair loss consultant, advisor or trichologist who can create a treatment plan with you.
