Will Coloring My Hair Cause Hair Loss?

Yes, dying your hair may cause hair loss. However, hair loss does not happen after the dying process, it leads to hair loss over time. 

Many hair dyes contain harsh chemicals. These dry out the hair by leaving it without moisture and cause hair breakage and loss. These chemicals are specifically ammonia and hydrogen peroxide.

If you experience allergic reactions after dying your hair, allergies can also lead to hair loss.  If you are allergic to all these chemicals, it will cause inflammation and irritation on your scalp. It means that your hair follicle is affected and you will see patches of hair loss after dying your hair.

The substance PPD (paraphenylenediamine) in hair dyes is a highly allergenic substance and can cause allergic reactions. 

Does Repeated Hair Dying Cause Hair Loss?

Yes, the repeated hair-dying process greatly damages the hair.

Hair dye is a substance that is harmful to the hair in itself, and doing this over and over again means that the hair is constantly exposed to the same chemicals, and this causes additional damage to the hair.

Does Dying Hair Often Cause Hair Loss?

Frequent hair dyeing causes hair loss. It leads to thinning hair, dry scalp, and hair loss. Dried and thinned hair cannot adhere to the scalp, causing hair loss.

Does Highlights Cause Hair Loss?

Yes, it causes hair loss by hair thinning and hair breakage. The highlighting kits include bleach and peroxide.

During the highlighting process, the hair cuticles lift and allow chemicals into the cortex. This means, highlighting chemicals damages the whole hair element. This will lead to hair breakage and thinning eventually. 

Hair starts to shed because of all the harm the procedure has caused.

Chemicals such as bleach or strong dyes including hydrogen peroxide used in the process are the reasons for weakening hair

Does Balayage Cause Hair Loss?

Yes, it can cause hair loss, but unlike the highlighting procedure, it is done to the ends of the hair. So, it does not directly harm your scalp, but it damages your hair.

Balayage mostly results in hair thinning; after that, it can break the hair, and then hair loss starts.

Does Box Dye Thin Your Hair?

Yes, it can thin your hair. There is a key factor to pay attention to. These are the ingredients of the dye. It is very necessary to read the box where the ingredients are written.

If it has ammonia, hydrogen peroxide, or other strong chemicals, it will definitely thin your hair.

The best scalp colorings for thinning hair are the ones that do not have hydrogen peroxide and ammonia. 

Does Root Touch Up Cause Hair Loss?

Can Bleaching Kill Hair Follicles?

Bleach applied to the scalp can irritate and dry out the hair, which can lead to hair loss. Inflammations that occur as a result of damage to the scalp can also reach a level that can prevent the growth of new hair.

Is Hair Dye Bad for Your Scalp?

Dying thin hair may be riskier than others. It can damage hair more easily, and this damage can be more visible than other hair.

So, if you have thinning hair, you should ask and show your hair to a professional to dye it in the healthiest way possible.

Why Does Dying Hair Cause Hair Loss?

Unfortunately, the dyes we use for our hair do not contain innocent hair dye ingredients. When these substances interact with our hair, they break the hair and cause them to shed. 

  • Ammonia
  • Hydrogen peroxide


Both of these chemicals can weaken the hair and cause them to break and shed. Ammonia, which allows the dye to penetrate into the hair, damages the hair.

On the other hand, the pigments in your own hair color are destroyed by hydrogen peroxide, and it also destroys the protein in the hair. This causes hair loss as a result of the hair being deprived of protein.

Is It Normal to Lose More Hair After Dying It?

It is normal to experience hair loss after the dying process. Because the hair has gone through a procedure.

Over-processing of the hair due to the hair interacting with the dye, the brush rubbing against the hair while dying, and the hair drying out after the process can cause the hair to fall out as if it has gone into shock.

How Much Hair Loss Is Normal When Dying Hair?

In normal situations, daily hair shedding is between 100-150 strands of hair. However, this number may be less when dying your hair. We can say that a maximum of 100 hair strands are shed.

What Hair Color Loses the Most Hair?

The rate of hair loss increases from color to color. We should especially emphasize that dark colors should not be used for hair. Dark colors can be the best hair color for balding. Hair loss after dying your hair black is inevitable.

The best hair dye for hair loss is light colors because it contains less metal. Therefore, we can describe it as less harmful. So, we should consider using natural hair dye alternatives.

Red and black tones contain a lot of metal, which is harmful to the hair. This excess metal causes hair loss. 

Does Dying Hair Damage Hair Growth?

Although hair dying does not completely damage hair growth, it can slow it down.

Since it does not damage the hair follicles, there is no such thing as completely damaging hair growth. However, dyes thin and break the hair, causing it to shed, and as the hair breaks, hair growth slows down considerably.

Does Hair Ever Grow Back Healthy After Dying It?

After hair dying, the hair grows. This type of hair loss is a temporary hair shedding. However, you can integrate some actions into your life that will contribute to healthy growth. Thus, the damage your hair experiences due to the chemicals it is exposed to is minimized. So, we can relate hair dye and hair regrowth.

❗DO PROPER HAIR CARE

❗AVOID OTHER HARSH CHEMICALS

Does Hair Get Thicker After You Stop Dying?

When you stop dying your hair, the damaged thickness and healthy appearance of your hair will recover over time.

When you stop dying your hair, your hair will not become thicker, it will just return to its previous state. Thus, the appearance of your thinning and damaged hair will reach a healthy appearance when properly cared for.

What Kind of Hair Dyes Do Not Cause Hair Loss?

Some types of dyes do not cause hair loss, and this is usually related to the ingredients of the dye. At worst, they cause the least possible damage to the hair. It is generally recommended to use such hair dyes.

    • TEMPORARY HAIR DYES: does not penetrate deeply into the hair fiber
    • SEMI-PERMANENT HAIR DYES: penetrates the outer layer of the hair
    • AMMONIA-FREE HAIR DYES: less presence of chemicals in the hair dye.

Can Dying Your Hair With No Ammonia Dye Cause Hair Loss?

Ammonia-free hair dyes can also cause hair loss, but using ammonia-free hair dye usually prevents the loss to a large extent and prevents the hair from wearing out.

 

The natural pH level of the hair should be in the 4.5-5.5 band. However, ammonia, which is a very harmful component, increases this pH level to almost 14-15. This is very harmful to hair health.

 

A high pH level opens the cuticles in the hair, causing moisture loss. Dryness begins in the hair, which leads to hair loss. In order to avoid this dryness and prevent the hair from becoming damaged and falling out, ammonia-free hair dye should be preferred.
