How to Keep Your Hair Straight

1. Conditioner

If you keep Googling ‘how to keep hair straight all day’, ‘how to keep straightened hair from firzzing in humidity’, and ‘how to get sleek, straight hair’, then stop and read this!

I naturally have wavy/curly hair that is very reactive to humidity, which means that I used to have an incredibly hard keeping my hair straight after straightening it, no matter how many times I straightened each section of hair.

I would spend double the time I normally would on straightening my hair to make sure it was pin straight and even then, the second I would step outside my hair would poof up and become frizzy and wavy.

BUT, once I started using a lot of conditioner and letting it sit in my hair for at least a few minutes, I noticed such a big difference in how my hair reacted outdoors.

I like to apply conditioner every time I wash my hair after shampooing. I squeeze any excess water out of my wet hair and then apply a generous amount of conditioner (about a table spoon) on my ends and the length of my hair, making sure to avoid my roots. I let it in my hair for about 5-7 minutes and then wash it out with cold water.

After using conditioner my hair was less frizzy and stayed straight for much longer. This is because conditioner adds hydration and moisture to your hair and helps eliminate frizz since your hair gets frizzy because its dry and lacking moisture. If you want straight hair without frizz, then you need to start including conditioner in your hair care routine.
