I got this for my husband who is suffering from hair loss at the crown of his head; the ingredients looked promising so we decided to give it a try. The brush tip application is good in theory, but he said that it was a little difficult to reach all areas of his scalp without also getting a bit of product on his hair. Formula is a bit greasy as well, so take this into consideration when deciding what time of day to apply. My husband wears hats everyday for work so that didn't much matter to him. The smell of this serum is definitely strange, not in the best way, but I never noticed it unless I went up to him to smell his head, lol. So, per the directions, he's been only using one pump per application, but he said it wasn't really enough to cover all the areas that needed to be covered 🤦♀️ so he should have been using more. The amount in the tube has also lasted him a little over a month, so I'm also wondering if one click isn't dispensing the correct amount. However, after over a month's use, he hasn't noticed a visible difference and I don't see a difference unfortunately either. I wouldn't count this completely out, because like many products it may take months before seeing results. At this time I just can't justify buying another tube at $50 to test out that theory.
