    Soft and shiny hair!

    I’ve never reviewed a product in my life but I seriously love this product.

    I have fine hair that gets dry on the ends and greasy up top less than 24 hours post washing. This product keeps my hair fresh into day 3, while it remains moisturized and best of all, sleek.

    This would definitely be my “bring to a desert island,” product.

    Thanks Agenda!

    My ride or die!!

    I NEVER blow dry my hair without this! The consistency is so light and I love the smell. Doesn’t leave your hair sticky or greasy at all!

    I have fine hair, but a TON of it. Until now, I have not been able to find any combo that worked to protect my hair and give volume at my roots. After trying everything else I figured I would give this a go. I was skeptical, but hopeful. Everything is so lightweight, I was able to get the benefit of the product without overwhelming my hair. Secondly, the root boost gives me lasting volume for a couple of day, I just hit my roots with a round brush/blow dryer and it perks back up. I did notice I need less product than it suggests, 1.5 pumps is all I need. It sounds silly, but this is life changing for me and man, what a confidence boost! Love it so much! Time to stock up!

    You HAVE to try these products!!

    My favorite hair product combination..Head Start and Big Plans Ahead! My hair has never felt or looked better, and that’s HUGE for me since I have struggled with thinning and fine hair for years. My search is now over!! Thank you Agenda!!

    My Favorite Product!

    I have very fine hair that is also frizzy so while I need product before blowdrying I need something light. I love that this combines two products, leave in conditioner and heat protectant, into one! I didn't think a leave in cream would detangle as well as a spray but I was wrong. My hair feels so smooth, soft, and tangle free.
