During this phase, you can expect about 10% recovery as the initial steps of hair regrowth begin. This stage often focuses on stabilizing hair loss, with noticeable reduction in shedding for most users. Results during this time will vary depending on the degree of hair loss you started with, as those with less advanced hair loss may see quicker signs of improvement.
By this point, you may notice up to 20% recovery, with subtle regrowth and thicker, healthier-looking hair becoming more apparent. Shedding should have significantly reduced, if not stopped completely, as the follicles respond to treatment. Keep in mind that individuals with more severe hair loss may experience slower progress during this phase.
Hair regrowth continues with up to 30% recovery, as new hair begins to fill in thinning areas and existing strands become stronger. Results at this stage depend on the severity of your initial hair loss, with those in the early stages of thinning likely seeing more visible changes compared to individuals with extensive hair loss.
Significant progress occurs beyond this stage, with up to 90% recovery for many users as new growth becomes fuller and more consistent. This phase is where the most noticeable improvements happen, but the timeline will vary based on your unique hair loss pattern and response to treatment.
