Hair Types and Plate Sizes
First, it is important to know your hair - what type of hair you have - coarse, thick, curly, short, or fine fragile. Different hair types require different hair straightener to do the straightening or styling job.
- If you have unmanageable thick curly hair, use a flat iron with 1.5 - 2 inch plates.
- If your hair is short with normal hair texture, go with a smaller plate like 1.25 inch hair straightener.
- For straightening fine hair, 1.5 inch flat iron can do the good job.
See the table below for plate size recommendation:
| Texture | Hair Length | Recommended Plate Size |
| Very coarse, thick, curly | Long (below shoulder) | 1.5 to 3 inch |
| Very coarse, thick, curly | Medium | 1.5 to 2 inch |
| Very coarse, thick, curly | Short | 1.25 inch |
| Normal | Long | 1.25 to 2 inch |
| Normal | Medium | 1 to 1.5 inch |
| Normal | Short | 1 or 1.25 inch |
| Fine, thin hair | Any length | 1 to 1.5 inch |
Further, if you are highly trendy and would like to try a variety of hairstyles, it would be good if you would go for multifunctional straighteners that help you to experiment different hair styles.

Hair Types and Temperature Setting
Second, you need to consider temperature settings of a hair straightener. Low temperatures would be ineffective to get the job done, and high temperature could cause heat damage on your hair. If a hair straightener comes with fixed temperature setting (without adjustable temperature), make sure if the temperature is good for your hair type. Now most flat irons have various temperature setting that lets you set a temperature good for your hair, but you still need to check the temperature range when you buy a hair straightener. See image below for a flat iron with right temperature setting.
- For damaged or thin hair, the temperature should not really exceed 120°C.
- For normal Hair, the temperatures should be from 160°C - 180°C to straighten it.
- For thick hair, the temperatures should be higher than 190°C - 210°C.

A temperature control should be added to the usability of your straightener giving you more control and peace of mind. You can increase the temperature up to your required temperature rather than finding out too late that your straightener is too hot for your hair.

From personal experience, CHI, Sedu and Solia can be trusted. Do not get a non ceramic, cheap hair straightener, it would eventually dry out your hair like you won't believe.
