In addition to the methods mentioned above, there are some other ways to lengthen eyelashes, such as using growth-promoting products and undergoing medical cosmetology treatments. Here are the specific methods:

- Latisse: It is a prescription medication in some regions. The main ingredient is bimatoprost, which can prolong the growth phase of eyelashes, making them longer, thicker and darker. However, it should be used under the guidance of a doctor, as improper use may cause side effects such as eye redness, itching and changes in iris color.
- Eyelash Growth Serums with Natural Ingredients: Besides those mentioned above, some serums contain natural plant extracts like green tea extract and ginseng extract. These are believed to have nourishing effects on eyelashes and may help promote their growth. Look for products with good reviews and reliable brands, and use them according to the instructions.
- Eyelash Transplantation: This is a more invasive but relatively long-term solution. It involves transplanting hair follicles from the back of the head or other parts of the body to the eyelid area. The transplanted follicles will grow new eyelashes, which can achieve a natural and long-lasting effect. However, this is a surgical procedure and requires professional evaluation and operation by a plastic surgeon. There are certain risks and complications, such as infection and bleeding. The recovery period also needs to be carefully taken care of to ensure the survival rate of the transplanted follicles.
- Platelet-Rich Plasma (PRP) Therapy: In this treatment, a small amount of the patient's blood is drawn and processed to concentrate the platelets. The PRP contains growth factors that can promote cell growth and tissue repair. It is then injected or topically applied around the eyelash area. The growth factors in the PRP are thought to stimulate the hair follicles of the eyelashes and promote their growth. However, this method also requires professional operation and may need multiple treatments to achieve better results.
