You can't actually train your hair to become straight. Your hair texture is determined by the shape of your hair follicles, which are genetically determined. This means that you can't permanently change your hair's natural texture. However, you can use various techniques to temporarily straighten your hair.
Here are some common methods:
1. Heat Styling:
- Flat Iron: This is a popular method that uses heat to straighten hair. Be sure to use a heat protectant spray to prevent damage.
- Blow Dryer: You can use a round brush and a blow dryer to straighten your hair while drying it.
- Hot Rollers: Hot rollers can be used to create loose waves or straight styles.
2. Chemical Treatments:
- Relaxers: These chemicals break down the bonds in your hair, making it straighter. Relaxers can be harsh on your hair, so it's important to use them with caution.
- Keratin Treatments: These treatments smooth out the hair cuticle, making it appear straighter and smoother. Keratin treatments last longer than relaxers.
3. Styling Products:
- Straightening Creams: These creams can help to smooth out frizz and make your hair more manageable.
- Hair Serums: Serums can help to add shine and reduce flyaways.
4. Other Methods:
- Braiding: Braiding your hair while wet can create a straighter look once it dries.
- Wrapping: You can wrap your hair in a silk scarf or satin pillowcase at night to reduce frizz.
Remember, it's important to be gentle with your hair and use heat styling tools sparingly to prevent damage.
