Hello, this product is for hair removal. It cannot be used for hair dyeing. 

Yes. This device uses IPL (Intense Pulsed Light) technology designed for safe at-home use. The built-in ice-cooling system helps reduce heat sensation, while smart skin tone detection supports safe energy selection. Always follow the user manual and perform a patch test before full treatment. 

This device is not recommended for pregnant users, people with sunburned or irritated skin, or those using light-sensitive medications. Avoid use on tattoos, very dark skin tones, or hair colors such as grey, white, or red. If unsure, consult a professional before use. 

For best results, use the device on the same area at regular intervals as instructed in the manual, typically on a weekly basis during the initial phase. Allow time between sessions for the skin to recover. 

IPL works gradually by targeting hair follicles during the growth cycle. Many users notice reduced regrowth and finer hair after several weeks of consistent use. Individual results may vary.
