When trying Hairfinitys serum I really had no expectations in mind. To be honest, I was at a desperate point in my hair journey due to a lot of protective styles and wig usage resulting in a receding hairline, I was simply just looking for any bit of progress. That’s exactly what I found with this amazing serum!! Using it every day and night, I was able to see these wonderful results within 15 days of my first usage. I now also have incorporated the serum into my pre-poo treatment the night before I wash. I saturate my scalp in the serum and now I notice less shedding (almost none) during my wash process. I will also like to mention because my hair is naturally curly, to ensure that the serum does not revert my hair back to curly I prefer to put the serum on my finger tip and apply it directly to my scalp which allows me to control the amount of liquid hitting my hair. With that also being said,you need to apply very little amount every day. This bottle will last me at least a month and a half which is definitely a bang for your buck.
