Prostaglandins have a hormonal-like effect on the natural growth cycle of eyelashes. They target the anagen phase of the eyelash growth cycle. This causes eyelashes to grow longer, thicker, and increase the amount of eyelashes grown.
2. Wavering Hormones. Hormones affect eyelash growth just as they can affect your hair growth cycles and an imbalance may cause your eyelashes to fall out, along with other hair — something that can occur while pregnant or postpartum.
Now for lashes, the hormone estrogen in the body affects their rate of growth and their thickness. The right levels of estrogen will grow thick and healthy hair whilst low levels of estrogen can lead to thinning hair.
Anagen phase—This is the growth phase when new hairs grow from eyelid follicles. Anagen usually lasts for 1–3 months and is what determines your eyelash length.
Oils such as vitamin E, castor oil, olive oil, and even petroleum jelly have a positive effect on eyelashes. Dip a disposable mascara wand in your choice of oil and coat the lashes from base to tip. Leave it on overnight. Be careful not to rub any oil into your eye.
Biotin is a B vitamin that is known for stimulating new cell growth, essential for regrowing fallen lashes. For this reason, a biotin deficiency can be linked to hair loss and, in turn, lash fall. Biotin can be found in eggs, almonds, cauliflower and other vegetables, as well as Vitamin B supplements.
Studies also show that estrogen does not only protect against hair loss but stimulates new growth as well. The estrogen/hair growth connection is especially evident during pregnancy when women experience thicker, healthier hair due to higher estrogen levels in their bodies.
High estrogen is triggering subtle changes in your face that make you feel more beautiful to yourself, and it's making both men and women perceive you as more attractive, too, shows a 2009 study in the journal Biology Letters.
Aging – Prostaglandin is the hormone that signals your eyebrows to grow. As we get older, our natural prostaglandin production declines. That's why it's common around menopause for our eyebrows to thin, grow a little longer, become coarse and even change color.
Testosterone, a male-dominant hormone, increases the quantity and quality of body hair, including eyelashes, which helps make women's eyelashes appear longer and thicker.

Biotin: This is the most common active ingredient in over-the-counter eyelash-growth serums, which are often marketed as conditioning treatments.
Lower estrogen and progesterone levels: Estrogen and progesterone stimulate hair growth, which is why pregnant women—who are producing extra levels of these hormones—tend to experience thickening hair during their pregnancy.
The hair cycle and hair follicle structure are highly affected by various hormones. Androgens—such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)—are the key factors in terminal hair growth.
No matter how you like to eat it, you'll also be giving your body an extra boost of vitamin D, known to help our lashes and lovely locks grow longer and stay healthy.
