Have you ever noticed some people’s hair starts to get thinner or disappear in certain spots? This is called patterned hair loss. It happens to men and women, and it’s a very common thing. Today, we will discuss what patterned hair loss means, why it happens, and what treatments are available.

What Is Patterned Hair Loss?


Patterned hair loss means hair falls out in certain shapes or patterns on the head. For boys and men, it often starts at the front or top of the head, making the hairline move back or a bald spot appear. For girls and women, hair usually gets thinner over the top of the head but the hairline stays the same.


This happens because of changes in the hair follicles, which are the parts of your skin where hair grows. These changes make the hair grow thinner and shorter until it stops growing. Patterned hair loss is mostly caused by genes, which means it can run in families.


Why Does Patterned Hair Loss Happen?


The main reason is genetics. If your parents or grandparents had patterned hair loss, you might get it too. It can start when you are young or later when you are older. Hormones, especially a type called DHT, also play a big role by making hair follicles smaller.


Sometimes, other things like stress, illness, or certain medicines can make hair fall out, but patterned hair loss is mostly about genes and hormones.


Treatments You Can Try at Home


If you notice your hair getting thinner, don’t worry. There are many treatments you can try, some you can buy without a doctor’s prescription. Here are a few popular ones:


  • Shampoos and Vitamins: Some shampoos have ingredients that help keep your scalp healthy. Vitamins like biotin and zinc can support hair growth, but they work best if you have a deficiency.


  • Healthy Diet and Care: Eating foods rich in vitamins and minerals, like fruits, vegetables, and proteins, helps your hair stay strong. Avoiding harsh hair treatments and brushing gently also protects your hair.


Medical Treatments with Strong Evidence


Some treatments have been studied a lot and show good results:


  • Minoxidil: This is a liquid or foam you put on your scalp every day. It helps hair growth and helps prevent further thinning. You can find it in stores as Regaine or other brands. It works best if you start early and keep using it regularly. An oral version is also available, which can be especially useful if you are unable to use topical treatments or you get side-effects, e.g. irritation.


  • Finasteride: This is a pill that blocks the hormone DHT. It can stop hair loss and even help hair grow back. It needs a doctor’s prescription.


  • Platelet-Rich Plasma (PRP): This treatment uses your own blood to help hair grow. Doctors take a small amount of blood, spin it to collect platelets, and then inject it into your scalp. Platelets have growth factors that help hair follicles work better.


There are different types of PRP, like ACP and ACPmax. ACP is a basic form, while ACPmax has more platelets and might work better for some people. PRP is safe because it uses your own blood, but it can be a bit uncomfortable and needs several sessions.


  • Regeneron Activa: This is a newer treatment available at Welbeck. It combines special growth factors and stem cells to help hair grow. It’s still being studied but shows promise for people with patterned hair loss.


Genetic Tests Like Fagron


If you want to understand your hair loss better, genetic tests like Fagron can help. These tests look at your DNA to see if you have genes that make you more likely to lose hair. Knowing this can help doctors choose the best treatment for you.


Seeing a hair specialist


If you or someone you know is worried about hair loss, seeing a hair specialist like is a great idea. Dr. Bryan can look at your scalp, talk about your family history, and suggest the best treatments for your hair. He can also explain how to use treatments safely and check your progress.



Tips to Keep Your Hair Happy


  • Use gentle shampoos and avoid hot water.

  • Eat a balanced diet with plenty of vitamins.

  • Avoid tight hairstyles that pull on your hair.

  • Protect your scalp from too much sun.

  • Talk to a doctor if you notice sudden or patchy hair loss.



Patterned hair loss is common and can feel worrying, but many treatments can help keep your hair healthy and growing. Whether you try over-the-counter options like minoxidil, explore medical treatments like PRP or Regeneron Activa, or get advice, there are ways to manage hair loss with care and confidence.


If you think you might have patterned hair loss, the next step is to talk to a hair specialist. They can guide you to the right treatment.
