How to Choose the Best Straightening Shampoo

Here are a few DOs and DON’Ts when shopping for a straightening shampoo:

  • DO choose a shampoo with keratin protein in it to strengthen the hair strands.
  • Choose one with silicone in it because silicone reduces frizz and makes hair more manageable.
  • DO choose one with conditioning oils, especially coconut and argan oil.
  • DON’T use a shampoo with a lot of sulfates in it. While it’s good for lather, it can strip moisture out of the hair and make it drier.

Benefits of Using a Straightening Shampoo

Straightening shampoos work wonders with curly, frizzy, and wavy hair. They work to reduce frizz, add shine and gloss to your hair, keep hair straighter for a longer period of time, and make detangling a lot easier.

They won’t necessarily make the hair super straight, especially if your hair is very curly and coarse, but you’ll likely be surprised by how much smoother your hair is with regular use of these shampoos.

They also decrease the risk of heat damage by reducing the length of time it takes to straighten hair using heat styling tools.

Other Tips to Straighten Your Hair at Home without Heat

If you’re curious about how you can make your hair straighter at home without using heat, here are a few tips to follow:
  • Use plastic rollers on your hair
  • Use natural oils such as almond, macadamia, and coconut oil
  • Blow-dry using cold air
  • Sleep with your hair wet and wrapped up
  • Use products specifically made to make the hair straighter, including shampoo, conditioner, hair mask, etc.
  • Learn to wrap your hair each night, and try sleeping on a satin pillowcase
