DHT Blockers vs PRP for Hair Loss: What’s the Difference and Which One Is Right for You?

Hair loss affects millions of people and can have a big impact on confidence. At Cheshire MediGlow in South Manchester, we offer personalised, science-led treatments that support both scalp health and hair growth.

Two common and effective hair-loss treatment strategies at our South Manchester clinic are:

• DHT blockers – targeting the hormonal cause of hair thinning

• PRP (Platelet-Rich Plasma) – using the body’s own regenerative potential

Although both can improve hair growth, they work in very different ways. In this blog, we’ll explain how DHT blockers work, how they differ from PRP, and why someone might choose one over the other, or even use both together.

What Is DHT and Why Does It Matter for Hair Loss?

Dihydrotestosterone, or DHT, is a hormone that can cause hair follicles to shrink in people who are genetically sensitive. This process is a major driver of androgenetic alopecia, commonly known as male or female pattern hair loss.

Excess DHT at the hair follicle causes:

• Shrinking of hair follicles

• Weakening of the hair shaft

• Thinning of hair density

Targeting DHT is a key strategy for preventing further hair loss, especially in early stages.

What Are DHT Blockers?

At Cheshire MediGlow, Altrincham, we use Dutasteride Mesotherapy to block DHT directly in the scalp. This treatment involves micro-injections of a low-dose dutasteride solution combined with regenerative exosomes, copper tripeptide, biotin, and B-vitamins.

By delivering the treatment directly into the dermal papilla (the part of the follicle responsible for hair growth), we inhibit the enzyme that converts testosterone into DHT. This local delivery reduces systemic exposure compared to daily oral tablets while still achieving excellent results.

Dutasteride mesotherapy is suitable for men and women experiencing:

• Receding hairlines

• Thinning crowns

• Diffuse hair shedding

It is also effective for peri- and post-menopausal women, who often have increased sensitivity to DHT due to hormonal changes.

Benefits of Dutasteride Mesotherapy

• Targets DHT at the source, addressing the root cause of pattern hair loss

• Re-energises dormant follicles with exosomes and peptides

• Reduces shedding within weeks and improves hair density after 3–4 monthly sessions

• Minimal downtime – injections are tiny, and you can wash your hair the next day

• Lower systemic risk compared with daily oral dutasteride tablets

  
  

What Is PRP for Hair Loss?

PRP (Platelet-Rich Plasma) is a natural, regenerative treatment that uses your own blood to stimulate hair growth.

During treatment:

1. A small sample of your blood is taken

2. The sample is processed to concentrate platelets

3. The platelet-rich plasma is injected into the scalp

PRP promotes hair growth by:

• Stimulating dormant hair follicles

• Improving blood circulation to the scalp

• Strengthening existing hairs

• Supporting natural regrowth

Unlike DHT blockers, PRP does not affect hormones but instead focuses on repairing and regenerating the hair follicle environment.

DHT Blockers vs PRP: How They Differ

Feature	DHT Blockers	PRP
Primary Mechanism	Blocks DHT locally at the follicle	Stimulates regeneration and circulation
Targets	Hormonal cause of hair loss	Follicle repair and growth
Onset of Benefits	Weeks to months	Months (gradual improvement)
Use Case	Early-stage pattern hair loss	Early to moderate thinning; regenerative support
Delivery	Scalp injections	Scalp injections
Side Effects	Very low	Very low (uses your own blood)

Why Choose a DHT Blocker Over PRP?

DHT blockers may be the preferred choice if:

• Hormonal factors are the main cause of your hair loss

• You want a preventative treatment targeting DHT at the source

• You are experiencing receding hairlines, thinning crowns, or diffuse shedding

• You prefer a treatment with low systemic exposure compared to oral medication

When PRP Might Be a Better (or Complementary) Choice

PRP may be preferred if:

• Hair follicles need regeneration

• You want a non-hormonal treatment

• You want to strengthen and revitalise weakened follicles

• You are looking for long-term scalp and hair health

Can You Use DHT Blockers and PRP Together?

Yes. Combining treatments often provides the best results.

• DHT blockers protect follicles from hormonal shrinkage

• PRP strengthens and regenerates the scalp environment

Together, they address both the root cause and follicle health, giving a comprehensive solution for hair loss.

Which One Is Right for You?

The right treatment depends on:

• Your pattern and stage of hair loss

• Whether hormonal factors are dominant

• Your preference for natural vs medication-based treatments

• Your goals and lifestyle

At Cheshire MediGlow, we create personalised plans based on your hair loss pattern and underlying causes, whether that includes DHT blockers, PRP therapy, or a combination. Dutasteride mesotherapy and PRP are both effective treatments for hair loss, but they work in different ways. DHT blockers target the hormonal driver of hair loss, while PRP focuses on regenerating and repairing the hair follicle environment. Many patients benefit from combining both approaches for optimal, long-term results.
