Pantene Pro-V Expert Collection AgeDefy is a range of products meant for mature women and promises to strengthen the outer hair so it feels fuller and has less breakage. There are four products in the range; shampoo, moisturiser, repair and thickening treatment. They recommend you use all four products for a period of fourteen days to gain the full effect. I've been using them for slightly longer and my hair feels fuller, is much less flyaway, brittle, and there's less of it in my brush after drying.
The Advanced thickening treatment is a light, non-sticky spray that goes onto wet or dry hair, they recommend fifteen pumps of the spray, massage the treatment into your hair and then finish as usual - that's it. If I'm in a real rush and don't have time to wash my hair in the morning I wet it, spray in the thickening treatment, dry it and it looks good enough. That's quite something when your hair's as fine as mine.
This isn't a miracle cure and I have no idea about any of the science but; as a woman of a 'certain' age I'm still proud of my hair and I'll do whatever I can to make it look better and keep it healthy. I'm happy that my hair feels fuller, looks in extremely good condition and seems to be breaking off less since using this range of products and that's my honest recommendation.
