Loving The Rootist Strengthen Concentrated Conditioner. As a runner, my hair tends to get tangled and matted from the moisture and sweat during my runs, and this made it easy to detangle and comb through while leaving my hair feeling nourished and silky smooth. The best part is that it doesn’t leave any greasy residue- you know what I’m talking about- that pesky product buildup associated with most conditioners. It just leaves it manageable, soft, and smelling fantastic. I was also pleasantly surprised to see that it only took me a five minute blow dry to get my hair to look great (see the “after picture I attached)- typically I have to go through 20 minutes under the heat and then subject my hair to the flat iron- but not with The Rootist. I recommend this for anyone who is looking for an effective conditioner that leaves hair feeling silky smooth without product buildup.
