Lash Extensions are completely safe and non-intrusive when done properly – it is important that the natural lashes are carefully separated and not glued together, that the extension is not too long or heavy for the natural lash to support and that the client follows proper hygene instructions.
If cared for properly, eyelash extensions can last up to 3 to 4 weeks before a fill-in is necessary. With regular maintenance they will last indefinitely.
Your natural lashes typically grow out and turn over every 45 to 60 days on average. Maintenance is recommended every 2-4 weeks.
