Does colouring or tinting my hair cause hair loss in males or females?
Hair colouring is a regular part of many beauty routines, yet it continues to be surrounded by unnecessary fear, particularly the idea that it causes hair loss. Many clients worry that their dye habit is behind their thinning hair. The truth is, hair colour doesn’t interfere with the follicle responsible for growth.
What it can do, however, is cause damage that’s often misunderstood. In this article, I’ll walk you through what happens when you colour your hair and how to tell the difference between breakage, sensitivity, and actual hair loss.
Impact of hair dye on the hair follicle
Hair dye acts on the hair shaft, not the follicle. The follicle, buried under your scalp, is where hair grows. Because tinting doesn’t affect this root structure, it cannot cause hair to stop growing.
However, highlights, when not applied correctly or monitored closely during the process, can weaken the hair. This would then be termed breakage, where perhaps too high a percentage of peroxide is used or left on too long for the particular natural colour. It is not usually breaking from the root.
Breakage vs Hair Loss
Many people mistakenly attribute breakage to hair loss. If chemically treated hair snaps near the root, it may look like it’s falling out, but your scalp is still producing new strands.
Common causes of breakdown include:
- Bleach left on too long
- Colour overlap on already-processed hair
- Lack of moisture and post-colour conditioning
This damage is visible but temporary and manageable with the proper care, especially in the Summer months, when heat products are reduced.
Allergic Reactions to Hair Dye
After using dye, you might have an itchy, red, or burning scalp. This is often an allergic reaction, especially if a patch test wasn’t done first.
This type of reaction is called contact dermatitis, and although uncomfortable, it rarely causes permanent hair loss.
If you do experience symptoms:
- Take an antihistamine
- Apply Aloe Vera to calm irritation
- Avoid further chemical exposure
At Shuna Hammocks Trichology, I often treat these cases using soothing, steroid-free care treatments.
Could Scalp Burns Lead to Hair Loss?
Yes, severe chemical burns, such as those caused by bleach, can damage the scalp. In some cases, this may cause temporary shedding or, in rare instances, long-term loss if the follicle has been scarred.
But this is highly uncommon when professionals colour hair and post-care instructions are followed.
For such instances of hair loss and improper and unprofessional conduct, I offer my expert witness services. Contact me for further details.
