I am currently 24 weeks pregnant and notice that my hair is not as thick and lustrous as it was prior to pregnancy so when I seen the Pantene Age defy Advanced Thickening Treatment I was excited. I have been using this product exclusively for a week and although I have only noticed a very slight thickening of the hair I have noticed my hair looks more healthier and shinier which was enough for me to run out and purchase another bottle. Since I am in my late thirties I am also considering purchasing the Pantene Age Defy shampoo and conditioner to see if they will work just as good.
