I’m having laser done in 2 days with the GentleLase Pro U laser machine, and I’m wondering what the optimal settings for thin hair are. I have thick hair on my body, but im also doing areas where my hair is fine, and in certain areas fine and long. Its still dark though. Is the best efficacy achieved with the 18mm spont on highest fluences just like with thicker hair, or is it best to use the 15mm or 12mm spots and increase the fluence accordingly? Also, I’ve heard shorter pulse duration is more effective for fine hair. Is this true? Thank you in advance for your answers
Short pulse width.
