- Topical Minoxidil 5% to 10%: It is a vasodilator, which means it widens blood vessels to improve blood flow to the follicles, causing more hair growth. It's commonly used on the eyebrows to increase eyebrow density for a more thick, masculine look. Use Minoxidil with a derma-stamp anywhere from 0.5mm to 2mm to increase it's effectiveness. Minoxidil without a derma-stamp will be much less effective. Derma-stamp once or twice a week and apply Minoxidil on your eyebrows every morning and night. Only apply this to your eyebrows (or scalp) and do not get it any where near your eyes as it's vasodilating effects can easily cause eye issues. Wash it out immediately if it gets in your eye.
- Bimatoprost (Latisse) 0.03%: It works by extending the anagen (growth) phase of eyelash hair follicles, causing thicker and longer lashes. It's safe for the eyes unlike topical Minoxidil but it does have a risk of darkening your eye color if you don't have T50 eyes. It's biggest risk is the way it nukes orbital fat around the regions it's applied which is why you should apply something like Vaseline around the area above your eye near the upper eyelid and all around as a protective barrier. Only use 1 drop of Bimatoprost and get a swab to apply to the upper eyeline. It's recommended to not use it on the lower eyeline as it can cause the under-eye region to look tired through removing orbital fat there and darkening the skin. Using it more than once a day will not speed up results. Be careful.
- Topical Cyclosporine 0.05%: "Woah what's that?" is a question some of you might be thinking right now. It's a superior to both Minoxidil and Bimatoprost. In short, it induces the anagen (growth) phase and inhibits catagen (regression) phase of hair follicles. Press
HERE for specifics. Thanks @depersonalized. He basically explains that it's superior to Minoxidil and Bimatoprost simply due to targeting hair growth in more pathways than them.
It's biggest risk topically is ocular burning in 17% of users. Otherwise, it seems quite safe and should be applied like Bimatoprost with something similar to a swab. It can be applied to both the upper eyeline and the lower eyeline.
