Hair loss can be an embarrassing issue for many people and is quite widespread. For instance, between 40% to 50% of men and women suffer from Androgenetic Alopecia or APA in Canada, as of 2025.
But there is no need to panic, since you can opt for many non-invasive, innovative hair restoration treatments to undo the damage. These treatments involve the use of platelet-rich plasma, exosomes, micropigments, and gene manipulation, to name a few elements. They target the hair loss-causing genes and regenerate the hair follicles through several means.
Let us explore them in detail below.
Which Treatments Can You Opt for Hair Restoration?
You can opt for treatments like the following:
1. PRP
Platelet Rich Plasma or PRP for hair (PRP capillaire) is a revolutionary treatment that involves using a patient’s own blood to stimulate hair growth.
Consider the table below for a better idea.
| Step | What Takes Place During The Step |
| Blood Drawing | Your dermatologist will draw a small amount of blood from your arm and place it in the centrifuge. |
| Centrifuging | The centrifuge will spin quite fast, causing the blood to separate into platelet-rich plasma, platelet-poor plasma and RBC. |
| Concentration | Your dermatologist will draw the platelet-rich plasma and concentrate it further. |
| Injection | After its concentration, they will inject the platelet-rich plasma into the required areas on the scalp. |

You should expect to see your hair completely regrow within a year. However, you will require 4 to 6 such shots if you want to get full results.
2. Mesotherapy
Opting for mesotherapy for your hair in Montreal is another way you can grow your hair. It involves injecting Calcium, Magnesium, Iodine, Zinc, Copper, Potassium and Selenium into the scalp to stimulate hair follicle growth.
During the treatment, the dermatologist will clean and disinfect the affected areas on the scalp. They will then inject the mineral-rich mixture into the target areas. After injecting it, they will massage your scalp to spread the mixture evenly.
You will require eight separate sessions for this treatment, as the dermatologist will inject one shot every week.
3. Hair cloning
Hair cloning involves the replication of hair follicles and transplanting them into the affected areas. This treatment is currently in the experimental stage, but it is set to be a revolutionary treatment once commercialized.
The current measures being explored under hair cloning are stem cell technology and follicle banking. As per a 2023 review, stem cells have been shown to stimulate the growth of hair follicles to correct alopecia-induced hair loss.
Follicle banking refers to harvesting between 100-120 hair follicles and then cryofreezing them to prevent them from aging. These follicles can then be used for multiple treatments later on.
4. Exosome therapy
Exosomes are tiny vesicles that are secreted by cells.
These vesicles contain signalling factors and growth factors that stimulate the growth of hair follicles. Prior to the treatment, exosomes are obtained from mesenchymal stem cells, which give them tissue damage repair properties.
They are then purified and injected into the target areas with the help of fine needles. You will require multiple sessions for the treatment to be effective. Do consult your dermatologist about the necessity of multiple sessions.
5. Scalp micropigmentation
Scalp micropigmentation is a non-surgical hair restoration technique. It involves the administration of special pigments that make your hair look fuller.
These pigments reflect your hair colour and skin tone and are prepared after your consultation. Prior to the treatment, your scalp will be cleaned, following which the dermatologist will inject the pigments with a microneedle.
6. Hair regeneration therapy
Hair regeneration therapy combines traditional hair transplant and regenerative medicine. It involves the use of stem cells and PRP for hair (PRP capillaire) to stimulate hair growth. Before the treatment, the dermatologist will extract stem cells from your abdomen or your flanks through liposuction.
You’ll be told to rest for a while after this extraction. After that, the dermatologist will inject the stem cells into the affected areas on your scalp to stimulate hair growth. This procedure should not take more than 3-4 hours.
You should expect to see complete results in about 12 months. However, the exact timeline will depend on your response to the treatment.
7. Gene Therapy
Gene therapy involves the manipulation of specific genes to ensure continued hair growth. It is currently an experimental technique and involves the use of miRNA and siRNA.
SiRNA gene therapy uses Small Interfering RNA to change the sensitivity of hair follicles to DHT or Dihydrotestosterone, which causes hair loss. MiRNA gene therapy uses microRNA to stimulate the growth of aging hair follicles.
8. 3D Bioprinting
3D bioprinting for hair involves using advanced cells and biomaterials to create custom hair follicles to stimulate hair growth. The dermatologist first extracts cells from regions in the scalp, where follicles are present.
These follicles are then mixed with a solution that promotes cellular growth by simulating an ideal cell growth atmosphere. The solution is deposited into a bio-printer, which creates the follicles.
The follicles are allowed to mature in a particular environment and then injected into the scalp in a minimally invasive manner.
9. Nanotechnology
Nanotechnology involves using nanoparticles to deliver targeted medications like Minoxidil and Finasteride to the affected areas on your scalp. Nanoparticles are particles with a size of 10 to the power of minus 9 metres.
This approach is effective since it can target individual hair follicles for effective hair growth. However, there is limited safety-related information related to this treatment, so you can opt for safer ones like PRP capillaireinstead.
Wrapping Up
There are many innovative hair growth treatments you can try to grow your hair again after hair loss. The treatments covered above are just the tip of the iceberg, and there are many other treatments that you can explore.
These involve using wearable devices, AI, scalp microbiome research and CRISPR-based hair growth. Ultimately, the type of treatment you go for will depend on your preference and your dermatologist’s advice.
