There are many reasons why people look for solutions for female hair loss, from traction alopecia to pattern baldness and hair loss caused by stress or illness.
Perhaps one of the most unusual reasons for hair loss and damage was experienced by one of the most successful and popular singers of the last decade.
Before she was a globetrotting superstar, Ariane Grande was a child actor and the star of the TV show Victorious, where she played Cat, a student with exceptionally bright red hair.
Several years after the show and its follow-up Sam And Cat ended, Ms Grande explained in an interview that her signature ponytail hairstyle came about because of hair loss and hair damage caused by four years of intense bleaching and dyeing of her hair every fortnight.
Eventually, her natural hair did grow back and she has worn it down when she appeared on the cover of Vogue magazine, but it does pose a very important question.
Can dyeing your hair cause hair loss and why is this the case?
The answer, reassuringly enough for many people who love to experiment with styles and shades, is that no, hair dye alone does not cause hair loss in most situations, but there are situations where it might contribute to problems that could cause hair loss.
How Hair Dye Works
Hair dye materials target the individual strands of hair and either penetrate or deposit colour depending on whether it is a bleach or permanent hair colouring product or a temporary dye.
In either case, even relatively intense dyes will not damage your hair in normal use, even if you are someone who regularly tops up their dye jobs.
However, there are a few relatively rare cases where hair dye and hair loss may be part of the same sentence.
Allergic Reactions
Despite the strength of the product, hair dye does not tend to react to the scalp, but if it does one of the many symptoms of inflammation is some degree of hair loss.
In exceptionally rare cases, an allergic reaction can cause hair to fall out, along with flaking skin, redness, soreness, sensitivity, irritation and other signs of an allergic reaction.
It tends to be an immediate response and it is important to get in touch with your doctor to minimise any damage and avoid health complications.
Contributions To Hair Breakage
Whilst hair dye does not cause hair to fall out outside of allergic reactions and speeding up hair loss that was already going to happen, what it can do is cause damage to the hair strands themselves, which can cause breakage, tangles and a greater risk of accidentally pulling out hair.
Over a long time, this is likely to be far more noticeable, as well as if you regularly use straighteners, curlers or other heat-based styling tools.
This was likely the issue Ms Grande had to deal with; it was not just the frequent dyeing but also the styling and everything else that went into the hair and make-up of a television show.
Ultimately try and make sure you nourish your hair after dyeing it by using a deep conditioning treatment, as well as shampoos and conditioners designed with colour-treated hair in mind to keep it feeling its best.
