The problem of long-lasting curling of eyelashes is a problem that many people will encounter. Here are some possible reasons why lashes don't curl permanently and how to fix them:
Lash texture: Some people's lashes are naturally straight and less prone to curling. This may have to do with the texture and structure of the lashes. Soft, thin, straight lashes are easier to restore and less curled to maintain. The solution is to use an eyelash curler before mascara, curl the eyelash curler as much as possible, and then apply mascara, which can help maintain the curling effect of the eyelashes.
Using the wrong mascara: The texture and formula of your mascara can also affect curling. Choose a mascara that has a curling effect, and preferably a waterproof one, as they usually have better curl retention. Waterproof mascara resists moisture and sweat to help keep lashes curled.
Incorrect application technique: When applying mascara, make sure to use the correct technique. Starting at the root of lashes, roll the brush upwards to curl lashes from the root. You can apply multiple coats when applying, but make sure each coat is completely dry before applying the next one to avoid the lashes from becoming heavy and falling.
No Eyelash Curler: An eyelash curler is an important tool to help curl your lashes. Using an eyelash curler before applying mascara can pre-curl your lashes and increase the volume of your lashes. When using an eyelash curler, gently clamp the root of the eyelashes, hold it for a while, and then release it. Eyelash curlers should be used on clean lashes to avoid pinching or breaking lashes.
Too Dry Mascara: Too dry mascara can make it difficult to curl your lashes. Make sure your mascara is fresh and closes well after application to prevent premature drying. If your mascara dries out or expires, consider replacing it with a new one.
Humidity and environmental factors: Humidity and environmental factors can also affect the curling effect of eyelashes. In a humid environment, eyelashes may be prone to straightening. Use a waterproof mascara for extra protection. Also, use a lash growth primer or lash setting spray to increase the longevity of your lash curl.
If you've tried the above suggestions and the problem persists, consider consulting a professional makeup artist or beauty consultant, who may be able to give personalized advice and tips to meet your needs.
