What You Should Know About Coffee for Hair: 5 Coffee Hair Dye Side Effects

Are you curious about using coffee for hair?

Perhaps you’ve heard about coffee hair dye side effects or the promising effects of using coffee for hair growth.

Well, let’s talk all about it in this post – the uses, benefits, and possible side effects of using coffee for hair. We’ll start with the most popular fact; coffee hair dye side effects.

Coffee Hair Dye Side Effects

Coffee is an easy-to-get hair ingredient with many benefits.

But like every other hair ingredient, there are possible side effects.

The good thing about coffee is that you can avoid these side effects if you take the necessary precautions.

The first precaution to take is to know the possible side effects.

So here you go, here are the possible side effects of using coffee for hair:

1.    Hair Loss

Right. Coffee can help you deal with hair and promote hair growth but watch out! It may also cause hair loss.

This could happen if you overuse coffee for your hair.

Applying coffee to your hair too frequently can distort your hair growth process and cause hair loss. 

Aside from applying to your hair, drinking too much caffeine can also stunt your hair growth.

To avoid this possible effect, you should apply coffee to your hair at most once a week.

2.    Chemical Damage

Using instant coffee for your hair can introduce strange chemicals to your hair because instant coffee is processed and contains preservatives.

To prevent this side effect, you should use fresh ground coffee beans as often as possible when preparing your coffee hair mask.

3.    Burns

This can happen when you use hot coffee for your hair.

As you can expect, hot coffee will severely burn your hair and scalp.

The way out is always to allow the coffee to cool down before applying it to your hair or scalp.

4.    Staining Effect

Coffee has staining effects. That property is what makes it an effective natural hair dye.

While this is a benefit in itself, it could be undesirable if your hair is light-colored and you do not want any alteration to its color.

There is no way to prevent coffee from staining your hair with black so the best thing is to avoid using coffee for your hair if you would not want it darkened.

5. Hair Dryness

Coffee makes your hair dry and weak when you overuse it.

So you want to be moderate with its use.

As mentioned, you should not apply coffee to your hair more than once a week.

Benefits of Coffee for Hair

Caffeine is the main ingredient in coffee. And you probably know that consuming too much caffeine is bad for your health.

It is also bad for your hair. But that’s for excess use.

Moderate amounts of coffee can do your hair a whole lot of good. Some of these benefits are:

1.    Improved Hair Growth

Research has shown that caffeine is a natural hair growth stimulant.

Applying coffee to your hair can help foster its growth, especially when you use it for a scalp massage.

A coffee scalp massage would promote blood circulation within your scalp and exfoliate your scalp, removing dead cells that may slow down hair growth.

These factors contribute to your hair growing faster, healthier, and thicker.

2.    Control Hair Loss

Hair loss, especially when it’s alopecia, can be annoying if not depressing.

If your hair keeps falling off excessively, here’s some good news.

Research published by the National Library of Medicine mentions that caffeine (the main ingredient in coffee) may be used as an alternative to drug-based treatment of alopecia.

This is because caffeine can easily penetrate the scalp and trigger hair growth.

Coffee is an excellent ingredient for dealing with hair loss.

3.    Prevents Damage

Coffee contains antioxidants.

Apart from preventing diseases in the body, antioxidants also prevent the hair from being damaged.

By applying coffee to your hair regularly, you’ll be fortifying your hair to fight against breakage, dryness, and other hair issues that could lead to damage.

4.    Improves Hair Look

A common antioxidant in coffee is flavonoids.

This antioxidant prevents your hair from looking dull.

Coffee also helps to seal in present moisture, and add shine to your hair.

This makes your hair bright-looking, moisturized, and shiny.

5.    Dyes Hair

One of the most intriguing benefits of coffee for hair is its ability to dye your hair strands.

If your hair has become grey with age or gotten lighter due to damage, coffee is one of the safe ingredients that can come in handy.

This study shows that using coffee is a convenient way to reduce greyness. Although it may not intensely darken your entire hair, coffee can help your hair look darker than its current state.
