I shaved a small part of my eyelashes, will it grow back and if so how long?

Hello,
Thank you for your question. You can use Latisse to grow your lashes quickly. However you might consider wearing false lashes to make it less obvious, Good luck!

They should go back in 3-4 months. In the mean time, Latisse in combination with prp and Viviscal can help regrowth. See an expert for a formal evaluation. Best, Dr. Emer

Eyelashes are replaced every 3-4 months. So, provided you did not cause injury to the eyelashes, and did create inflammation, you should find your eyelashes return to normal density by 3-4 months. There is nothing that can speed up this otherwise normal physiologic process.

Eyelash gone, don't worry, it will grow back; if there was trauma to the area, there will be a one month delay and then it will grow back at 1mm per week; So you must be patient; you may want to get some Latisse to stimulate quicker growth.

Hi there and thank you for the inquiry,
Latisse is a great product that can help grow your lashes longer, thicker and darker over the course of several weeks. You can expect to see noticeable lengthening after 3 months and also please note that your lashes will eventually regrow to their natural length with or without eyelash lengthening products. Consult with a cosmetic plastic surgeon for an in-person evaluation. 
You can try to wear individual eyelash extensions or false eyelash strips for an immediate solution.
