If it hurts, it’s too tight. 🤍

Tight buns, braids, ponytails and extensions can pull on your roots and cause hair loss over time. It’s about the tension, not the style.
Caught early, hair can recover, but ongoing pulling can cause permanent loss.
Give your roots a little breathing room. Loosen styles that hurt, take breaks, and don’t wait for thinning to show.
If your hairline is receding or your scalp feels sore, bumpy or crusty, get it checked. Your comfort matters.

Six months of progress following a 2,495-graft hair transplant. 🌱

At this stage, new growth is becoming more visible, although the transplanted hair is still developing in thickness, texture and density. Further maturation commonly continues over the following months.

Ground work. Four scalp habits with something behind them.

1. Wash every second day, at least. The fear of overwashing did not hold up.
2. Check the active, not the claim on the front.
3. Leave it on for five minutes. Rinsing straight off wastes most of it.
4. Keep going. Flaking comes back, so it is maintenance, not a course.

Can red light really help with hair loss? 🔴

Research suggests that certain low-level light therapy devices may improve hair density in some men and women with pattern hair loss when used consistently over time.
But not all devices deliver the same treatment. Wavelength, power, light source and treatment schedule all matter.
LLLT is generally used as part of a broader hair-loss plan after the cause and pattern of thinning have been properly assessed.

Swipe through for what the research found and what to check before choosing a device.
