Red hair is beautiful and reacts nicely to the sun. It is the rarest hair color, and it is often wavy or curly. Have you noticed most red-haired people have curly hair? Why do redheads have curly hair?

  • Red hair is caused by extra cells on the outside and less on the inside 
  • Red hair follicles tend to be thicker than other colors of hair
  • Curly hair is warmer, and redheads come from ancestrally-cold climates

Is there science behind red hairs always being curly, or is this something that is pure coincidence?

We’ll explain it all below!

What Causes Redheads To Have Curly Hair? Why Do Redheads Have Curly Hair?

The reason redheads have curly hair might be explained by science, or it might just be a pure coincidence. 

Now there are two reasons why people that have red hair have curls.

Traditionally, curls are believed to result from more hair cells on a hair follicle’s convex side, the outer edge. There is a smaller number, a lesser percentage on the concave side.

As a result, fewer cells are on the inside, resulting in a shorter edge, drawing the follicle inwards and producing the curl. 

It is believed that red curly hair is due to the length of the cells on both the concave and convex sides of each hair strand.

There is a size difference between the compact cells on the inner side and elongated cells on the outside.

Did you know that curly hair will keep you warmer than straight hair. Curls are a defense against heat loss!

What Makes Hair Red?

Occasionally, somebody inherits two gene variations controlling the pigments in their hair. For example, a person whose hair is red can’t produce dark pigments because of those genetic variations.

Hair color is also regulated by genes controlling hair texture and shape.

So it isn’t just about what type or how much pigment your body makes that determines your hair color, but also the type of hair, the porosity level, etc. 


The Best Way To Care For Curly Red Hair

1. It Should Be Diffused

Hair dryers with diffusers attached are the best way to dry curly hair. Your curls will look more defined this way, so spray soft finishing hair spray both before and after.

It takes some practice and time to blow dry with a diffuser. 

The first time you use a diffuser, grab large chunks of hair and ensure the diffuser is held close to the head. Here’s a good explainer on diffusing curly hair:

2. Anti-Frizz Serums

You should choose styling products containing anti-frizz ingredients, such as mousse, serums, or oils. Since the 80s, curly redheads have used mousse to define their hair.

Make sure you apply a reasonable amount, otherwise, your hair will become crunchy.

3. Oils and Hair Masks

Maintaining healthy, moisturized red curly hair is easy with oils and hair masks. Several oils can be used to achieve the best outcome, such as avocado oil, olive oil, or (our favorite) coconut oil for hair.

When washing your hair, rub the oil on the scalp and the ends of your hair. 

By wrapping your hair in a warm towel, you’ll allow the pores on your scalp to open up, increasing the penetration of the oil. Wrap your hair for 20 minutes at least, but preferably overnight if possible.

Then, rinse it out with cold water and shampoo. For continually healthy curls, apply an oil hair mask each week. 

Don’t overdo your hair masks. This can lead to oily hair.

Instead, use quality hair masks and oils to ensure they do what they are designed to do. You will also get better ingredients without as many chemicals.

4. No-Poo

Hair oils can be stripped from the curls by shampoos. Frizz can result from this. Co-washing is also an option, which is a conditioning wash. It is sometimes called no-poo shampooing because no shampoo is used.

Simply put, you skip the shampoo and use only conditioner.

It almost feels like second-day hair when it comes to smoothness and manageability.


Redheads Have Thicker Hair 

In comparison to other colors, red hair strands are thicker. Therefore, redheads often seem to have a lot of hair, despite having fewer hair strands.

For example, there are about 140,000 strands of hair in the average brunette and about 90,000 in the average redhead.

Conclusion

There is something special about redheads! A red head of hair is quite attractive and uncommon. You might have straight red hair, but you could be the special one with curls too. 

So enjoy those red curls and flaunt them with pride.
