You have damaged hair, well I know this sounds mad but there is something that really works, it is a product called Mira hair oil, it is actually very powerful it is all natural and safe for kids and adults alike. If you have damaged hair it will take care of it for you in a few weeks. Not only that it makes hair grow faster and thicker and grows the dead hair outIt has no smell or color; it comes with a shampoo called GRO which also helps boost hair growthUse their conditioner too if you want but I didn’t. I simply just washed my hair with regular herbal shampoo after I used the Mira hair oil And my damaged hair grew out and I also grew an inch plus in a month!!
