I've been to a plastic surgery, 6mo ago, removing a mole from my forehead. Currently there is a pink-red scar there, anyway to make it heal faster?

No. Let nature take its course. Trying to alter the coloration is likely to make matters worse. You may consult a lady friend about using make up to conceal the mark.
Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex.
