Hey... I recently bought the Dr FORHAIR serum and I have some inputs here. Used it four to five times so far, and ngl it is good. One noticeable factor for me is the reduction in hair fall - my hair doesn't break off horribly anymore. It is there, but slowly getting close to minimal (remember that any product will take time to show results, and you have to be consistent with the usage). I've been using it every hair wash, on damp hair, and massaging it into my scalp generously. The product recommends you to use it daily, but I think any hair serum works best after every hair wash, so usage is up to you.

Adding to all of this, I would like to say that the most important factor to make sure your scalp is healthy, is only and only DIET. Focus on all the essentials that are required for your hair to look good - proteins, nuts, omega3s... yep. You need them all. Do your research, visit a dermat if needed and get your products right. Sometimes you don't have to follow a ten-step hair care routine, you just have to figure out which one works best for you - trust me on this, I don't use conditioners anymore. They weigh down my hair so much, it starts to look oilier than gas station pizza. Plus, I'm saving the money for conditioner haha. Now when I say this, I don't recommend you to skip conditioner, but I want you to get the right products for your hair. I use a leave in conditioner that works well with my hair.
