As the new school year approaches, many are turning to hair dye to express their individuality. However, hair dyes contain chemical ingredients that can damage the scalp, so caution is essential when dyeing hair.
What are the risks of hair dyeing?
1. Damage to hair
Hair dyes contain irritating chemicals that cause visible damage to hair, such as breakage, hair loss, dryness, and split ends. Proper hair care is essential after dyeing. Additionally, dyes can irritate hair follicles, leading to inflammation, thinner hair, and follicle atrophy.Once hair follicles undergo necrosis, the process is irreversible and may even lead to permanent hair loss.
2. Damage to Internal Organs
Substandard hair dyes may contain heavy metals. These metals can enter the bloodstream through inhalation or skin absorption, circulating throughout the body and damaging internal organs. The kidneys and liver are particularly vulnerable, potentially leading to kidney failure and liver cirrhosis.
3. Triggers allergic reactions
Most commercial hair dyes are chemically synthesized substances prone to causing allergies, exacerbating existing allergic symptoms. To achieve rapid coloration, dyes often contain aromatic compounds that not only induce allergies but also alter normal cellular DNA. The more vibrant the dye color, the greater the potential health impact.Additionally, frequent use of hair dye can lead to liver damage, osteoporosis, and skin cancer.
How to care for hair after dyeing?
1. Apply Vaseline
Apply Vaseline before dyeing to protect the scalp and create a barrier. First, conduct an allergy test: apply a small amount of dye to the inner elbow or behind the ear, cover with clear tape, and leave for 48 hours.If redness, swelling, or a burning sensation develops during this period, it indicates an allergy to the dye, and its use should be avoided. After dyeing, monitor your scalp closely. If swelling, itching, or other allergic reactions occur, seek medical attention promptly. Neglecting these symptoms may lead to follicle necrosis.
2. Allow three months between dyeing sessions
To minimize irritation to the scalp and hair follicles, wait at least three months between dyeing sessions. Frequent coloring damages hair quality. Avoid washing your hair the day before dyeing to preserve natural scalp oils that protect hair. Additionally, never apply dye by washing your hair, as this allows the dye to come into direct contact with the scalp.
