Hi....dear , Thanks for choosing HCM., Trichoton or Curlzvit are same , but manufacturer is different..., 1) TRICHOTON.....Product from MED MANOR..., It contains Boitin and Minerals..., Biotin....... is necessary for hair growth....., There are many sources of biotin...... such as brewer s yeast..., brown rice, bulgur, green peas, lentils, oats, soybeans, sunflower seeds, and walnuts....., It is present in some shampoos, so you can use shampoos, which contain biotin.., only side effect is Vaginal infection ...other side effects are..., not enumerated..ok..., 2) CURLZVIT.....product from CANAXIA..life lab..., It contains Boitin, Vit E , Zinc and minerals.., Boitin is B complex vitamin..it is also called B7.., 3) SIDE EFFECTS.....Long usage of vitamin B7 (biotin) along with vitamin B5...., that caused a life-threatening condition called eosinophilic pleuropericardial effusion...., The condition promptly subsided once the treatment with vitamin B7 and vitamin B5 was stopped..., There is a possibility that the combination of the two vitamins in high doses caused the condition..., but it is very rare..., So use either TRICHOTON or CURLZVIT...for long time..., is safe and very effective..., Along this Topically use......Minoxidil and Aminexil 5% .., will give good result ok...good luck
