We all want them and we all want them to look and last as long as possible. Aftercare/home care of your lashes is very important. It's best to wait at least 24hrs before showering, working out, swimming or any activities that produce aspiration. This is in part do to the way the adhesive bonds and cures with the extension to your natural lash. If the curing process is too fast or to slow then there can be problem, that being a poor bond. In my office I regulate the humidity to keep it at safe levels. This is done with a humidity and temperature meeter. This allows for best control of the office environment. I can ether turn up the AC or turn it down or use a humidifier or a dehumidifier. (Thats why I don't do house calls. I need the humidity to be precise.)
After leaving your lash appointment make sure if at all possible to keep the humidity around you at fair level for the first 24hrs if at all possible. Life is life and sometimes we can't always control everything...but just try your best. After the 24hrs use the recomended aftercare products. This is very important because, not all cleansers are alike. The cleanser I have chosen for your lashes is safe. It has no oils, parables, sulfates or carcinogenic. (Having the potential to cause cancer.)
