Which Methods Are Effective for Hair Growth? A Doctor’s Perspective

September 19, 2025

Hair growth is possible, but only when supported by treatments that are backed by medical science. Among the most effective options are Minoxidil and Finasteride, which are FDA-approved for treating hair loss and have strong clinical evidence. Advanced procedures like Platelet-Rich Plasma (PRP) therapy and microneedling with serums also stimulate dormant follicles and improve scalp health. New-generation solutions such as Exosome therapy including brands like ASCE+, Hanheal, Hair Pro Bio Skin, Lucidor, GFC Cell, Exovex and Exohealer are showing promising results in hair regeneration. In addition, Low-Level Laser Therapy (LLLT) devices have been proven to increase hair density by improving blood circulation in the scalp. Choosing the right method depends on the individual’s condition, but modern medicine now offers multiple effective ways to restore thicker, healthier hair.
Before discussing treatments, it is important to understand why hair falls out. Common causes include:

Androgenetic alopecia (male or female pattern baldness): Genetic and hormonal influence leading to gradual thinning.
Telogen effluvium: Hair shedding triggered by stress, illness, or nutritional deficiencies.
Alopecia areata: An autoimmune condition causing patchy bald spots.
Poor scalp health: Dandruff, infections, or inflammation.

The possibility of regrowth depends on whether hair follicles are still alive but inactive (dormant) or completely destroyed. Dormant follicles can often be reactivated, while destroyed follicles cannot grow hair again.

1 Derma Roller (Microneedling for Hair Growth)

A derma roller is a device equipped with tiny needles that create micro-injuries on the scalp. This process stimulates blood circulation and the release of growth factors, which may promote hair follicle activity.

Effectiveness: Studies show that when combined with topical treatments like minoxidil, derma rolling can significantly enhance hair growth. It is particularly helpful in cases of androgenetic alopecia (pattern baldness).
Limitations: It must be used carefully to avoid infection or scalp irritation. Professional microneedling sessions are generally safer and more effective than at-home rollers.
You can purchase Derma Roller and Hair Growth Serums in Pakistan to boost scalp health and stimulate natural hair regrowth. We can use Dermaheal HL, Hair Pro Bio-Skin (Made in Spain), and Otesaly H PDRN for effective hair loss treatment and scalp revitalization.

Microneedling + Serums (Derma Roller)

Creates micro-injuries in the scalp, increasing blood flow and absorption of serums.
When combined with PRP, minoxidil, or peptides (like Dermaheal HL, Hair Pro Bioskin, Otesaly PDRN), studies confirm better results than minoxidil alone.

2 Onion Oil

Onion oil has gained popularity in natural and traditional remedies. It contains sulfur, antioxidants, and certain nutrients believed to support hair health.

Effectiveness: Some small studies and anecdotal evidence suggest that onion juice may help reduce hair thinning and encourage regrowth by nourishing hair follicles and improving circulation.
Limitations: Results vary greatly between individuals, and the evidence is not as strong as with medical treatments. Additionally, some people may experience scalp irritation or allergy.

3 Platelet-Rich Plasma (PRP) Therapy

PRP involves drawing a patient’s own blood, processing it to concentrate the platelets, and injecting it into the scalp. Platelets contain growth factors that can stimulate dormant hair follicles.

Effectiveness: Multiple clinical trials have shown that PRP is effective in slowing hair loss and promoting regrowth, especially in cases of early-stage androgenetic alopecia.
Limitations: It requires multiple sessions, can be costly, and results depend on the patient’s condition and overall health.

4 Hair Transplant Surgery

Hair transplant is a surgical method where hair follicles are taken from the donor area (usually the back of the scalp) and transplanted to thinning or balding areas.

Effectiveness: It is the most permanent and predictable solution for significant hair loss. Modern techniques such as FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplantation) give natural-looking results.
Limitations: It is invasive, costly, and requires a skilled surgeon. It is best suited for patients with stable hair loss and sufficient donor hair.

5 Hair Exosome Therapy

Exosomes are tiny vesicles (microscopic messengers) derived from stem cells. They carry growth factors, proteins, and genetic material that signal hair follicle cells to repair and regenerate. In hair restoration, exosomes are injected into the scalp to stimulate dormant follicles and improve the hair growth cycle.

Effectiveness: Early clinical studies and patient experiences show that exosomes may enhance hair density, thickness, and quality, especially in people with early to moderate hair loss. Compared to PRP, exosomes potentially deliver a higher concentration of growth signals.
Advantages: Non-surgical, minimal downtime, and may show faster results than PRP.

Limitations: Still a relatively new and evolving treatment. Long-term studies are limited, and the therapy can be expensive. Effectiveness also depends on product quality and technique, as not all exosome preparations are the same.

So, Is Hair Growth Possible?

Yes, it is possible! but with the right treatment, at the right time.

If you act early, non-surgical options like PRP, exosomes, derma roller, and medications can give excellent results.
If baldness is advanced, hair transplant is often the only reliable solution.
Natural remedies (like onion oil) may support scalp health but should not be relied upon as the sole treatment.

Final Advice
If you are experiencing hair loss, do not wait too long. Early consultation with a dermatologist or hair specialist is crucial. With proper diagnosis, timely intervention, and realistic expectations, regaining fuller and healthier hair is indeed possible.
