How Long Does PRP Last for Hair Loss? What to Expect from Treatment

PRP (platelet-rich plasma) therapy has emerged as a popular treatment approach for hair loss conditions like androgenetic alopecia. But how long do the benefits of PRP last? Read on to learn what to expect.

How Long Does PRP Last for Hair Loss?

For most patients, the positive effects of PRP on hair growth tend to last between 12-18 months after receiving the injections. To maintain the benefits, maintenance sessions are needed approximately every 6 months to 1 year.

Why the Effects Are Temporary

PRP doesn't produce permanent results for two main reasons:

  • The growth factors in PRP gradually degrade and lose potency over time.
  • PRP doesn't alter the underlying hormonal causes of pattern hair loss.

This means ongoing maintenance is required to sustain results. Think of PRP as giving your hair follicles a temporary boost and support.

Factors That Influence Duration

How long PRP results last depends on:

  • The number of treatments received - More sessions increase duration.
  • Consistency with maintenance plan - Sticking to schedule optimizes longevity.
  • Individual response - Some respond better than others.
  • Severity of hair loss - Mild cases may see longer lasting results.
  • Concurrent use of other therapies like minoxidil or laser devices - Can prolong effects.

What Are the Expected PRP Treatment Phases?

PRP for hair loss typically follows three phases:

Initial Treatment Phase

  • 3 sessions 4-6 weeks apart
  • Kickstarts the process and stimulates follicles
  • First visible improvements around 4 months

Maintenance Phase

  • Session every 6-12 months
  • Maintains and extends the initial improvements
  • Prevents regression between treatments

Adjustment Phase

  • Modify frequency based on individual response
  • May need sessions more or less often
  • Keeps treatment tuned to your needs

What Are Realistic Expectations from PRP?

It's important to have realistic expectations when using PRP for hair regeneration. PRP can:

  • Thicken existing hair and increase density
  • Stimulate inactive follicles to grow new hairs
  • Slow further hair loss
  • Improve scalp health

However, PRP usually won't:

  • Completely restore lost hair
  • Permanently stop hair loss
  • Grow hair in completely bald areas
  • Alter male or female pattern baldness genes

Results are gradual and variable between patients. Consistency with maintenance is key.

What Happens If You Stop PRP Treatments?

If PRP injections are discontinued, any regrown or thickened hair is likely to gradually revert over 6-18 months. Hair loss will resume its natural progression.

Why it’s important to stick to the maintenance schedule if you want to retain results long-term. Missing maintenance sessions normally leads to reversal of any improvements.

Should PRP Be Used Alone or With Other Treatments?

Using PRP alongside other treatments like minoxidil or low level laser can enhance and prolong results. The stimulatory effects of PRP complement other approaches well.

Combination therapy is common, although PRP can also be used alone. Discuss your options with a hair restoration physician to develop an integrated treatment plan.

The Bottom Line

For those considering PRP to treat hair loss, be prepared for a long-term commitment. While not a permanent fix, staying consistent with maintenance PRP every 6 to 12 months allows patients to retain results for years. Working closely with a specialist and managing expectations are key to success with this progressive therapy.
