Can hair dye cause hair loss?

Much evidence has shown that hair dying compounds can cause alopecia. In fact, this is due to the chemicals in the dyes.

Hair structure

A single hair has 3 layers which are cuticle (the outer layer), cortex (the middle layer), and medulla (the inner layer). Each one of them has its own role in maintaining the best condition of the hair. The cuticle is the defensive layer, the cortex preserves moisture and nutrition, and the innermost layer is the medulla. Chemicals in hair dyes are believed to break through and damage the layers.

Why does hair dyeing lead to hair loss?

Permanent hair dyes and temporary hair dies are included with ammonia and peroxides whose purposes are to bleach the natural hair color and give a color change. Both of these compounds can cause damages to the natural hair due to their affecting hair follicles and cuticle.

Permanent hair dyes with bleaching agents may result in permanent hair loss if the follicles are damaged too severely to renew the cycle of new hair strands.

The temporary hair-dyeing substances (or semi-permanent hair dyes) don’t really bleach the natural color of the hairs but too many times of changing hair colors over a short time can leave the hair short of nourishment and rest. If the hair is not looked at well after hair dyeing processes, hair thinning may become a real issue and permanent hair loss can happen.

How does hair dyes cause hair loss?

As already mentioned, the chemicals contained in the formulas of hair dyes are risk factors against the hair biological structure.

  • Ammonia

The cuticle is to protect hair shafts. For further penetration of dyeing chemicals, Ammonia has got the function of loosening this outer layer and weakening the protection of the hairs. As a result, hair shafts become more vulnerable and hair breakage is likely to happen.

  • Peroxide

Hydrogen peroxide plays the role of lightening the color of the hair for the new color to be visible and as desired. The compound can also damage the cuticle to get the dye through to the hair cortex and make the hair more frizzy and dry. Without proper treatment afterward, colored hair will experience much hair breakage and have to wait for a long time for the natural hair to grow again. What’s worse is if you tend to put your tresses through too many processes of hue changing over a short period, this can leave the hair damaged severely and the consequence is permanent hair loss.

Aside from Ammonia and hydroperoxide, the other chemicals in hair dyeing substances also cause breakage to hair to some extent. They may put your tresses in a dry and frizzy condition or even create a lack of nutrition for hair follicles leading to scalp health deterioration and of course, hair loss.

  • Stress

Stress is detrimental to our mind, body, and even our hair thickness. Someone that goes through constant pressure and anxiety in life may have to face hair loss as the hormones are badly affected. In this case, doing meditations and taking time to relax is necessary. Consulting a therapist should be considered if the conditions show adverse signs.

  • Medications or medical conditions

If you just see some hairs in your shower drain, it is okay but if your hair loss gets out of control and you see your scalp losing unusual large amounts of hair over a long time, you may need to ask real experts’ advice about it. The hair loss can come from a medical condition and you need to pinpoint it as soon as possible. In some cases, hair loss can be a side effect of some pills that you are using. You can ask your doctor for another alternative medication that doesn’t cause hair fall.

  • The natural hair growth cycle

Sometimes the hair loss is not bad news at all. Maybe it is just time for the hair follicle to renew its circle of shedding the old hair and letting the new hair shaft grow. The hair growth cycle is natural and there is nothing to worry about it.

To keep the hair healthy, you should follow a proper hair care treatment routine, have a healthy eating regime and limit the use of your hairdryer.
