Eyelash loss may occur due to the heat produced by the laser during the tattoo removal process. This heat can damage the hair follicles responsible for hair growth. However, the eyelash loss is usually temporary. Once the follicles recover, the hair should grow back. However, if the laser damages the hair follicle beyond repair, the hair loss could potentially be permanent. This is not a common occurrence and is usually due to an incorrect technique or setting used during the procedure. If you've noticed significant eyelash loss following your laser tattoo removal procedure, it is recommended to consult with your dermatologist or the professional who performed the procedure. They can provide specific advice based on your individual circumstance and possibly recommend treatments to stimulate hair growth if necessary. In the meantime, avoid irritating the area or using makeup products that may interfere with the healing process. Please note that this is general advice and may not apply to your specific situation. Always seek professional medical advice for your concerns.
