The number one reason people give up on laser therapy is quitting too early. Hair grows slowly — about 1 cm a month — and follicles move through growth cycles that take months. Here's what a typical timeline looks like for someone with pattern thinning who uses their device consistently.
Months 1–2: nothing visible yet
You won't see new hair yet. Follicles are responding beneath the surface. Some users notice a temporary increase in shedding as follicles reset into a new growth cycle; it usually settles. Keep going.
Months 3–4: less shedding
The first change most people notice is less hair in the shower drain and on the pillow. Some see fine, short new hairs along the part or hairline.
Months 4–6: visible change
For people who respond, density improvements usually become visible in this window. Take photos in the same light and angle every month — changes are easy to miss day to day.
Months 6–12: building results
Hair continues to thicken. This is when you can judge fairly whether the device is working for you.
After 12 months: maintenance
Laser therapy keeps working only while you use it. Most people continue at the same or a reduced schedule to hold their results. ADD CITATION
