I have just finished my first bottle of the 30ml growth serum, and I’m unsure if I’ll purchase again. For context, I’m 23 years old and my hair type is extremely fine and prone to breakage. I have been religiously looking after my hair for a long time, but within the last 1.5 years I have had nano bead hair extensions. I use various hair products to help promotes hair growth and healthy ends, in conjunction to this serum. I decided to take out my hair extensions and put this serum to the test. I purchased this serum on 1/1/2025 and have the amount for about 2 more applications(currently 16/2/2025). Within the month and a half of using I can’t say I’ve seen any changes in my hair density or growth in length. I have stubborn hair that just does not grow quickly. However, the serum smells amazing and feels great on the scalp. I plan to test other serums before considering returning to this one. As I feel it hasn’t made the difference I expected from other reviews.
