Hair loss – the reasons behind

Hair loss – raise your hand if at least once in your life you thought about it and asked yourself “Why I am loosing so much hair?”.  For me, hair loss is a common issue and my hair is everywhere – on bedsheets, my clothes, boyfriends clothes, towels and on everything I touch. I have a lot of hair, and I even managed to clog our sink once because I did not notice how much hair I was brushing away.

Anyway, hair loss has been one of the most requested topics on my Instagram. Therefore, I collected all the information and tried to summarize it in a simple way for You.

Hair growth process

Hair growth is divided into three stages. Anagen, which lasts around 6-8 years and 80-90% of our hair are in the anagen phase. Next is catagen, which is only a couple of weeks long and around 1-2% of our hair in catagen. Finally, telogen that is final hair growth stage, for about 3 months and 10-20% of our hair in telogen. Once telogen is over hair falls out and the new hair follicle starts formating leading to the new hair. Overall, we want to keep our hair in anagen phase as it is growth phase and avoid catagen and telogen.



Surprise surprise, but stress is one of the key contributors to hair loss. I definitely noticed that with my hair. How does it work? Well, stress in our bodies causes a release of various mediators, also known as neuropeptides. These neuropeptides then affect different cells that start releasing more products that stop anagen phase and initiate catagen. Therefore, when we stressed we can notice unexpected hair loss.



Hormones are involved in controlling hair growth by regulating anagen/telogen cycles. Triggers such as the contraceptive pill, pregnancy, ovarian cysts, period loss, thyroid function can affect hormonal balance and lead to the hair loss. For example, increased production of testosterone causes the production of more dihydrotestosterone, which can suppress anagen phase. This is more common in men, yet this can also occur in women.

Dietary insufficiency

A healthy diet is also very important for hair growth. Deficiency in micronutrients such as vitamin D, B’s, iron, zinc can also lead to the hair loss. These micronutrients are essential in maintaining the healthy environment for the hair growth. However, please do not go and spend money on those MagicalHairPills as they are not worth it. You need to get checked if you are actually deficient in any micronutrients in order for them to work. Also, there is some evidence that too much of vitamin A can also initiate hair loss. Therefore, be careful with supplements and use them only if you actually suffering from low levels. There are plenty of documentaries and articles highlighting that constant use of vitamins does not help our bodies and can be toxic (or you can actually experience bad constipation, not attractive). Personally, I choose to eat well and get my micronutrients from food and better spend my money on fancy conditioner or a lipstick.


Immune system and scalp conditions

If you had a long and bad cold you might also experience hair loss. Any disease or stress to our bodies again activates various immune cells that can defend and heal our bodies. In doing so, immune cells release various mediators that can protect but also affect hair cycling. Therefore, healthy body and immune system are important for healthy hair.

I said this before healthy scalp means healthy hair. As such, changes in scalp pH or increase in dandruff can affect scalp and hair follicle health, which means hair loss.


Overall, our bodies are very unique, so as our hair cycling. I hope this has been useful and maybe gave you some answers or suggestions. In my upcoming post, I will share products that might control hair loss, so stay tuned. However, the best way to avoid hair loss is to love your body – choose the right foods and avoid stress. 
Have a wonderful day and love your hair!
  • Great tips! I recently changed up my diet a bit and I’ve noticed less hair in my hair brush 🙂 I’ve also got a decent conditioner now which really seems to be helping.

    Hey Laura! I am so glad I found your blog. Do you have an email sign up? I avoid shampoos with sulphates where possible, and this year is hopefully my year of healthy, shiny long hair! Do you tips apply to boys as well as girls?x

    • Thank you lovely!!! You can follow me on Twitter, Instagram (I like to share hair advice there a lot) and Bloglovin. If you have any hair questions about men hair just let me know, you can always DM me ! xxx

  • Thank you so much for explaining the science behind everything in such a simple way! Until now, I was never able to understand hair growth phases and when you write about them they just seem so easy!!! I am looking forward to the next part of the article as hair loss is the issue which affects me greatly. I was blonde for years but noticed that my hair for the last year or two didn’t grow much at all, it just kept breaking and snipping off, no matter how many great products I would use, which made me realise I needed to give it a break from bleaching. Only now, when got brown hair (which I don’t feel suits me well, anyway) it made me actually realise how thin it is and no matter what I do it only keeps getting worse. I’ve been to different doctors and trichologists and they have two theories- it’s either related to my hypothyroidism (I’m on hormones and my test results are perfect) or a male pattern alopecia. They initially gave me some medicines to use but they work in a tricky way: you use them every day and after 3 months your hair starts falling out even more, stops after a while and all seems to be fine, for the next 6 months you don’t have much hair fall out, new hair doesn’t grow though. What happens next is your body gets used to the medicine after a year, so you need to stop taking it for 3 months, which is when your hair starts falling out again. Then you’re back on the medicine and everything starts all over, which basically means there aren’t any medicines which would treat my condition, they could only slow down the process slightly which I’m not sure is worth the fuss with so many side effects they have. I got to the point when I am starting to think about hair transplant (not now but perhaps in a year or two?) as that seems to be the only way which has quite a big chance to bring the result I am hoping for. Would you, my darling, ever consider writing a post on hair transplants? Nothing immediate, just a suggestion as you are my only trusted source, I can’t resist the impression that soooo many doctors and ‘hair specialists’ are only after our money making us buy most expensive products taking advantage of our insecurities. Anyway, enough of moaning, I gave you a proper novel in here! Hope you have a beautiful day, hugs from sunny London 😉 Xxxxx

    • Honey Thank you so much for sharing your hair story with me. Personally, I do think it is related with your thyroid function as I spoke before with several dermatologists thyroid has a huge role in controlling hair growth. I think I mentioned before maybe it is worth trying Vitamin D, Biotin and Omega 3 supplements? There is some evidence that woman who experience hormonal and thyroid dysfuntion have weaker hair but usage of Omega 3 helps to slowly restore hair growth, yet it is very long process. Please, love you hair and don’t stress about it as you are beautiful the way you are !! Science is moving forward and I do hope one day everyone will have only wonderful hair days. About hairtransplant it is worth considering, yet it is not always a good “fix” as it can last for several years and then patient tends to experience hair loss again. however, thanks for suggestion as I think It would be great topic to talk about! xxx

      • Yes, you did mention Vitamin D, Biotin and Omega 3 and I’ve been religiously taking each of these supplements ever since so let’s hope in time I will notice some difference 🙂 Thank you for all your great suggestion and constant support you give me <3 <3 <3

    • Ahh thank you beautiful!!! I am very glad you like it and grateful for stopping by to read ! xxx

  • oh i loved this post. i lost quite a lot of hair last summer and it was scary. in the end i was lacking zinc and iron and it sorted itself out pretty quickly.

    • Ah honey I am so glad you found the reason why you were losing a lot of hair! It is always about thinking what is going on inside our bodies! xxx

  • Such an interesting post! I used to have such thick hair but as I’ve gotten older it’s definitely thinned out 🙁 On a separate note, I noticed that you’re posting from Vilnius! We were there last year and loved visiting the city xx

    • Maybe you should try something with panthenol as it is great in adding more thickness to the hair! And yes honey currently in Vilnius and so glad you enjoyed my hometown xxx
