What Makes PP405 Different From Minoxidil And Finasteride

Hair loss is one of the most common cosmetic and psychological issues worldwide. Androgenetic alopecia (AGA), or pattern hair loss, affects over 50 million men and 30 million women in the United States alone. 

The last decades had only two treatment options approved by FDA, minoxidil and finasteride. Although they are beneficial, they are limited with slow outcomes, incomplete regeneration and inappropriate side effects.

This has prompted researchers to look into newer ways of hair restoration. A potential drug is PP405, a novel small-molecule compound being developed by Pelage Pharmaceuticals, out of research at UCLA.

This blog discusses what makes PP405 different from minoxidil and finasteride, the mechanism of action, trial outcomes, user testimonials, side effects, and the expected date of availability, and how to get the best out of it when it becomes available.

What Is PP405 & How Does It Work?

PP405 is an oral, first-in-class, small-molecule drug that activates DHT-sensitive hair follicle stem cells by normalizing their mitochondrial metabolic processes. The hair roots need large amounts of energy to transform the inactive (telogen) state to the growth (anagen) state. 

With age or the stress of hormones or toxins, follicle stem cells become less efficient at producing mitochondria. This causes hair to become thin and leads to the complete shrinking of the follicle.

Mechanism of Action

PP405 inhibits the mitochondrial phosphate carrier (MPC). This increases the availability of ATP (adenosine triphosphate), the “energy currency” of the cell. Higher ATP levels rejuvenate follicle stem cells, enabling them to restart hair growth.

Unlike minoxidil which acts through vasodilation and finasteride which acts to reduce DHT (dihydrotestosterone), PP405 directly targets the stimulus of mitochondrial dysfunction, a root cause of follicle miniaturization.

In early testing, PP405 is shown to be able to stimulate hair follicle growth at a cellular level in less than 4 weeks. It is important to note that it has no impact on hormones and blood pressure and this aspect makes it potentially safer both with men and women.

What Is PP405 Made Of? (Molecule Breakdown)

PP405 consists of a proprietary, small-molecule that is known as JXL069, which is used to specifically disrupt mitochondria. Molecular features include:

• Structure: Phenyl-pyridine based molecule.
• Target: Against the mitochondrial phosphate carrier (MPC).
• Function: It boosts the production of ATP, decreases stress in the cell and improves regenerative processes.

In contrast to minoxidil and finasteride, that were re-purposed toward use in hair loss, PP405 was purposely designed, with the regeneration of hair follicles in mind. Such precision-targeted design makes it stand out in the hair restoration industry.

Who Is PP405 For?

PP405 is being tested primarily for androgenetic alopecia (AGA) but may have wider applications. Potential candidates include:

• Men and women with thinning or pattern hair loss.
• Younger patients in early stages of hair thinning.
• Women who cannot take finasteride due to hormonal risks.
• Patients sensitive to minoxidil irritation.
• Combination users: Those already using minoxidil, PRP, or microneedling but looking for enhanced results.

How Does PP405 Compare to Current Treatments?

The differences between PP405, minoxidil and finasteride may be observed directly to know what makes the former different. Both have been standard treatments but act through limited mechanisms.

1. Minoxidil: It expands blood vessels around the scalp and brings more oxygen and nutrients to follicles. Minoxidil works only as long as it is continuously applied.
2. Finasteride: It inhibits 5-alpha reductase enzyme, lowering DHT and reduces hair follicle shrinkage in men. It cannot be used by women of childbearing potential.
3. PP405: It recharged follicle stem cells by increasing mitochondrial energy. It may restore previously dormant follicles to active growth and acts independently of hormones, making it gender-neutral.

Timeline of Effects

• PP405: Cellular activity in 4 weeks.
• Minoxidil: Visible effects in 3–6 months.
• Finasteride: Noticeable results in 6–12 months.

PP405 vs Minoxidil vs Finasteride: A Comparison

There has always been a long comparison between PP405, minoxidil and finasteride. The table below summarises all the necessary differences between them. 

Feature	PP405	Minoxidil	Finasteride
Mechanism	Mitochondrial support & regeneration	Vasodilation	DHT suppression
Time to effect	~4 weeks (at cell level)	3–6 months	6–12 months
Hair Density Gains	~31% in 16 weeks (Phase 2a)	10–20%	15–25%
Side Effects	Mild scalp redness or itchiness	Scalp dryness, irritation	Sexual side effects (2–5%)
Hormonal Involvement	None	None	Yes (affects DHT)
Type of Treatment	Regenerative, energy-based	Symptom relief	Hormone-based

Benefits of PP405 for Hair Loss

Unlike traditional therapies, PP405 offers a regenerative and restorative pathway for hair follicle health. Its main benefits include:

• Targets Root Cause: Brings mitochondria energy back to life, which is key to follicles survival and regrowth.
• Faster Activity Onset: This makes it safe for both men and women compared to finasteride.
• Non-Hormonal Action: Makes it safe for both men and women, unlike finasteride.
• Improved Safety Profile: The trials resulted in just mild and transient redness of the scalp.
• Synergy With Other Treatments: Can be used together with minoxidil or microneedling to improve the effect.
• Clinical Efficacy: Phase 2a trials recorded an approximate 31 percent growth in hair density within 16 weeks, as compared to existing options.

Such advantages indicate that PP405 might not only be an alternative, but a first-line therapy to hair-loss after approval.

PP405 Clinical Trial Results

Clinical trial data becomes the most significant evidence for any new treatment. PP405 was the subject of a 16 weeks, Phase 2a trial involving 92 individuals with androgenetic alopecia.

Metric	Baseline	After 16 weeks	% Change
Hair Density (hairs/cm²)	95	125	+31%
Hair Shaft Diameter (µm)	62	68	+9%
Compliance Rate	–	95	–

Additional Findings:

• Mild scalp redness or itching in <10% of users.
• No systemic or hormonal side effects.
• Patient satisfaction rates were high, with many reporting visible improvement by week 12.

Compared to standard treatments, PP405 showed faster onset and greater density improvement, making it highly promising for future approval.

PP405 Before and After: User Experiences

While still in trials, some early users have shared insights into their experiences:

• Weeks 4–8: Tingling sensation, mild warmth on scalp, appearance of soft “vellus” hairs.
• Months 3–4: Noticeable thickening of hair shafts, improved density, filling of thinning areas.
• Hairline effects: Some users reported new growth along the frontal hairline, an area often resistant to treatment.
• Reduced shedding: Daily hair fall decreased significantly.
  

Case Example: In one male subject who experienced thinning in the early stages, a rate of about 25% thickening was evident at the completion of the 4 months. A female subject who experienced diffused thinning reported an entire hair volume improvement during the same period.

PP405 vs Minoxidil vs Finasteride: Side Effects 

Knowing side effects helps you choose the right product. Here’s how PP405 side effects compare with other treatments:

Drug	Common Side Effects	Systemic Effects
PP405	Mild scalp redness or itchiness (<10%)	None observed
Minoxidil	Dry scalp, flaking, burning	Rare full-body effects
Finasteride	Mood changes, sexual side effects (2–5%)	Yes – hormone-related

Delays can happen, but these dates help you plan for the future.

Tips to Maximize PP405 Hair Treatment

When it becomes available, these tips can help you get better results:

• Use Daily: Apply the treatment every day.
• Clean scalp: Wash and dry the scalp before applying.
• Skip Hair Products: The hair styling gel and creams will alter absorption.
• Live Healthy: Eat, sleep and handle stress.
• Stick To The Plan: Some changes take a few months.
• Try A Combo: Mixtures of minoxidil or microneedling can be safe.

Conclusion

In contrast to minoxidil and finasteride, which acts as symptomatic therapy, PP405 is based on resolving the cause of action, restoring cellular energy. Even clinical evidence indicates better efficacy, quicker effects, and not so many side effects.

There is speculation that PP405 will be publicly available by the year 2028. This might soon become a new choice for both men and women with thinning hair. Until then, however, patients are encouraged to stick with what is known to work.
