Depending on the cause of an infection, a patient might need to take medications to clear up any issues with the eyes before regrowth can take place. Once the eye and surrounding eyelid are healthy and free of swelling and redness, the eyelashes should be able to grow within weeks. There's no scientific evidence that castor oil results in longer lashes. If you use it, be careful not to get it in your eyes — just use a cotton swab to trace the oil along the roots of your lashes. Some people even leave this treatment on overnight. Had my eyelash extensions removed today after 2 straight years of constant fills. I am in shock! What kills me the most best drugstore lash serum 2024 is that I was reassured time and time again that extensions did not damage my natural lashes because they were being &8220;properly done.&8221; I am sure I was seeing the best lash technician in my area, yet the damage is UNREAL. I am almost certain that all extensions must do damage. My natural lashes are down to tiny nubs and it&8217;s very sad. However, I purchased cold-pressed castor oil as well as the Plume serum after reading your post and am excited to start the process of getting my natural lashes back to normal! Thank you for these suggestions!
