If you’re looking into hair loss with exosomes in riyadh(تساقط الشعر بالإكسوسومات في الرياض) therapy, you’re likely moving past standard topical treatments and into the "heavy hitters" of regenerative medicine. Unlike traditional hair transplants or daily pills, exosomes work on a cellular level by signaling your dormant follicles to get back to work.

Here is the typical physiological roadmap for what happens during those 90 days.

Phase 1: The Cellular Wake-Up Call (Days 1–30)

In the first month, you won’t see a "lion’s mane" in the mirror. This phase is all about the microscopic environment of your scalp.

• Reduction in Inflammation: Exosomes carry anti-inflammatory signaling proteins. If your hair loss is driven by scalp tension or inflammatory conditions, this is when the "fire" starts to go out.

• Prolonging Anagen: The primary goal here is to signal follicles to stay in the Anagen (growth) phase longer and exit the Telogen (resting) phase sooner.

• The "Shed" (Rare but Possible): Occasionally, weak hairs are pushed out to make room for the stronger, exosome-boosted shafts coming behind them. Don't panic—it's a sign of progress.

Phase 2: Structural Strengthening (Days 30–60)

By the second month, the focus shifts from signaling to actual building.

• Increased Diameter: You may notice your existing hair feels slightly "sturdier." This is because the exosomes stimulate the dermal papilla cells, improving the quality of the keratin produced.

• Vascularization: Exosomes promote angiogenesis (the formation of new blood vessels). Better blood flow means more nutrients are reaching the root, which is vital for the upcoming growth spurt.

Phase 3: Visible Emergence (Days 60–90)

This is the "Transformation" window where the math starts to favor the mirror.

• New "Vellus" Hair: You’ll likely see fine, baby-like hairs appearing in previously thinning areas (especially the crown or hairline).

• Pigment Restoration: Many users report that new growth appears darker or more vibrant because the melanocytes (pigment cells) are also being revitalized.

• The "Density" Peak: By Day 90, the cumulative effect of more hairs staying in the growth phase simultaneously creates a visible increase in scalp coverage.

Why the 90-Day Mark Matters

Hair typically grows at a rate of roughly 1.25 cm per month.

At nearly 4 cm of new growth, the hair is finally long enough to lay flat and contribute to visual density. This is why 90 days is the industry gold standard for assessing if a regenerative treatment is working.

Quick Comparison: Exosomes vs. Traditional Methods

Pro-Tip: Exosome therapy is often paired with microneedling. This creates "micro-channels" that allow the exosomes to penetrate deeper into the follicular layer rather than just sitting on the surface.
