How can I increase my hair density and restore hair loss?

Question

Hello doctor,

I used to have denser hair when I was younger. Also, I have thick individual strands.

Is it possible to increase hair density by stimulating new follicles?
Can treatments only thicken existing hair?
And I am wondering if that can be restored?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

Hair density depends mainly on the number of active hair follicles on the scalp and the thickness of the hair shafts produced by those follicles. In humans, the total number of hair follicles is largely determined before birth, so treatments generally cannot create completely new hair follicles. Most medical therapies work by reviving weakened follicles and increasing the thickness and growth phase of existing hairs, which can make the hair appear denser.

Since you mentioned that your hair used to be denser and that you experienced significant shedding three years back, along with vitamin D and iron deficiency, it is quite possible that some follicles temporarily entered a resting phase, a condition known as telogen effluvium. In this situation, the follicles are not destroyed; they simply pause growth and shed hair earlier than usual. The underlying triggers, such as

Nutritional deficiencies.
Stress.
Illness.

If they are corrected, many follicles can return to the growth phase, and hair density may improve over time.

Another consideration is early androgenetic alopecia, where follicles gradually become smaller and produce thinner hairs with each growth cycle. In such cases, treatments can help reverse follicle miniaturisation and increase hair thickness, which can significantly improve density even though new follicles are not formed.

Correcting iron and vitamin D deficiency is very important because both nutrients play a role in hair cycling. Once levels normalise, shedding often stabilises within a few months. Treatments such as topical Minoxidil, low-level laser therapy, platelet-rich plasma (PRP), and certain oral medications can help keep follicles in the growth phase longer and produce thicker hair, improving overall density.

It would be helpful to know whether your hair thinning is diffuse across the scalp or more noticeable on the crown or hairline, as that can help determine the most likely cause and the best treatment approach.

If possible, please share pictures of the scalp area from the centre parting and side parting so I can better guide you on whether it is androgenetic alopecia or telogen effluvium.

I hope this answers your query.

Please let me know if I can assist you further.

Thank you.
