Relash services replace the extension of lashes that have naturally fallen out. The latest you can book a fill is 3 weeks from your previous appointment and have at least 40% of your extensions left, If not you will be charged for a full set. If you’re unsure of the amount you have and need guidance on if you should book a fill or full set please reach out. After your 3rd fill in you will be required to pay a removal fee and will need to book for a full set.
