How about: "Effective Ways to Strengthen Your Hair".

To straighten hair roots, you can follow these steps:

Wash and Condition: 

Start by washing your hair with a straightening shampoo and conditioner. This will help to smoothen the hair cuticles and make the straightening process easier.

Apply Heat Protectant: 

Before using any heat styling tools, apply a heat protectant spray or serum to your hair to protect it from heat damage.

Blow Dry: 

Use a blow dryer with a concentrator nozzle attachment to blow dry your hair straight. Start by drying your hair upside down to add volume at the roots. Then, using a round brush, pull sections of your hair taut as you blow dry them to achieve a smooth, straight look.

Section Your Hair: 

Divide your hair into sections using clips or hair ties. This will make it easier to focus on straightening the roots of each section individually.

Use a Flat Iron: 

Take a small section of hair at the roots and clamp a flat iron close to the scalp. Slowly glide the flat iron down the length of the hair, pulling it taut as you go. Be careful not to hold the flat iron in one place for too long to avoid heat damage.

Repeat: 

Continue this process, working in small sections, until you have straightened all of the roots.

Finish with Serum or Oil: 

Once you've straightened all of the roots, apply a small amount of hair serum or oil to the ends of your hair to add shine and reduce frizz.

Set with Hair Spray: 

Finally, spritz your hair with a light hold hairspray to help set the style and keep your roots straight throughout the day.

Remember to always use heat styling tools responsibly and avoid excessive heat exposure to prevent damage to your hair
