Subaru Hair Dye Side Effects

Subaru hair dye, like many other commercial hair colors, may cause a range of side effects primarily due to the chemical ingredients it contains, including ammonia, peroxide, and paraphenylenediamine (PPD)[1][2][3].

  • Allergic reactions: Ingredients such as PPD are well-documented allergens. Symptoms can range from itching, redness, and swelling to severe contact dermatitis[2][3].
  • Irritable skin and scalp: Chemical exposure may cause burning sensations, flaky skin, discomfort, and dermatological reactions, especially in those with pre-existing skin conditions like eczema or psoriasis[1][2][3].
  • Hair breakage and loss: Ammonia and peroxide can damage the hair cuticle, leading to dryness, breakage, thinning, and increased hair loss[2][3][5][7].
  • Conjunctivitis: Hair dye touching the face or entering the eyes may result in inflammation or conjunctivitis (pink eye)[1].
  • Dandruff and moisture loss: Hair dyes can strip the scalp’s natural lipids, resulting in dryness and making the scalp more susceptible to dandruff[3][5].
  • Respiratory issues: Inhalation of certain chemicals like hydrogen peroxide during application may cause respiratory problems, including asthma[3].
  • Headaches and nausea: Some users report headaches or feelings of nausea, likely due to strong chemical smells and sensitivities[2].
  • Fertility and pregnancy risks: Chemicals like lead acetate have been tentatively linked to fertility problems, and pregnant women are advised to avoid hair dye due to potential risks to the unborn child[1][3].
  • Cancer risk: Early formulas of permanent dyes contained carcinogenic compounds. While many were removed, the debate over the long-term cancer risk remains unsettled, especially with repeated exposure[1][2][3].
  • Severe poisoning (if ingested): Symptoms are severe and systemic, including organ damage, nerve issues, or coma. Swallowing hair dye is potentially fatal and requires urgent medical attention[4].

Several Subaru hair dye user reviews and social media experiences confirm similar side effects, such as dryness, breakage, and the necessity of post-treatment conditioning to counteract chemical damage[6][7][8].

Precautions: Always do a patch test 48 hours before full application to check for allergic reactions. Use deep conditioning and treatments after dyeing to minimize damage, and avoid frequent coloring. Individuals with sensitive skin or medical conditions should consult a dermatologist before use[3][6][7].
