Can We Not Bleach Our Hair? The Pros & Cons Explained

Bleaching can lighten your hair, but it can also have certain effects on its texture and color. We'll discuss if you should — or shouldn't — bleach your hair and the potential benefits and drawbacks to consider before making the decision. If you're looking to achieve specific hair colour shades, you'll want to know why it's important to bleach your hair first.

Understand How Hair Colours Work

To understand why it’s important to bleach your hair before adding certain colours, it’s essential that you understand how hair colour works. The primary process of changing the colour of your hair is known as oxidation, and in order for the dye molecules to penetrate into the cortex of each hair strand, they must have a light enough base first. If this isn’t achieved by bleaching, then the desired shade simply won’t take hold.

What Colours Need To Be Bleached?

In general, if you’re looking to achieve shades of pink, red, purple, blue or platinum blonde, then bleaching is essential. Natural brunettes who want to become a honey blonde without pre-lightening should also consider bleaching as it can help avoid yellow and orange tones from forming. Additionally, those aiming for pastel shades will require pre-lightening before their desired colour is achieved.

Why Do You Need To Bleach Before Dyeing?

When it comes to using permanent dye or temporary colour rinses, bleach is necessary for achieving light shades without brassy tones. Bleaching gets rid of the natural melanin in your hair, and opens up the cuticles that protect your strands from absorbing unwanted colours. The lifting process also increases the porosity of the hair allowing it to easily take on vibrant colour and even create dramatic results. Without pre-lightening, you won’t be able to unlock the potential for bold shades as effectively as you would have done with bleach.

What is Hair Bleaching and How Does it Work?

Hair bleaching is a chemical process used to lighten the pigment in your hair. It’s often done to achieve a lighter, bleached look or to create base for color types like Highlights and Balayage. The bleach works by breaking down the natural melanin in your hair, making it lighter and allowing for more adventurous colors. However, it’s also important to note that this process can be damaging if done incorrectly so it’s best to carry out any bleaching treatments with professional consultation.

What Are the Benefits of Bleaching Hair?

Bleaching hair can lead to several benefits, including opening up the opportunity for creative color styles and removing existing color without having to cut your hair. In addition, it can also help you achieve effects such as changing a dark shade of brown to honey-blonde or bringing out subtle highlights in your natural color. Finally, bleaching can protect from further damage by lightening the weight of your hair which helps make it more manageable.

What are the Drawbacks of Bleaching Hair?

When bleaching hair, there are some potential drawbacks and risks to keep in mind. For example, the chemicals used in many salon-grade bleaches can be damaging to the scalp and hair cuticles, leaving your hair more susceptible to further damage. In addition, depending on the amount of lightening desired and natural color of your hair, you may experience limited success with no guarantee of achieving your desired effect. Lastly, if done incorrectly, harsh bleaching can lead to breakage and excessive shedding due to weakened strands and protein loss.

Tips for Minimizing Damage When Bleaching

When bleaching one’s hair, it is important to take extra steps in order to minimize the amount of damage done to the hair. Using a professional product meant specifically for bleaching can give you the best results with reduced risk of damage. It is also important to ensure that your strands are completely saturated in blonde-lift or toner, and be conscious of the length of time they have been processing. You should also limit re-bleaching sessions, as even though it will give you more dramatic results, it’s also more likely to cause further damage. Deep conditioning treatments are suggested as they can replenish lost oils and moisture while helping strengthen each strand of hair so it can withstand future bleaching.
