What is the symptopms of scalp contraindications and what are their effects colouring hair?
Scalp contraindications refer to conditions or factors that may make it inadvisable or even harmful to color your hair. These contraindications can include:
- Scalp conditions: Active scalp conditions such as eczema, psoriasis, or open wounds can be irritated or aggravated by hair coloring products. Coloring your hair during these times can worsen the condition and cause discomfort or further damage.
- Allergic reactions: Some individuals may have allergies or sensitivities to certain hair coloring ingredients, such as ammonia, peroxide, or PPD (p-phenylenediamine). These allergies can cause reactions ranging from mild itching and redness to severe swelling, blistering, and breathing difficulties.
- Pregnancy and breastfeeding: While there is limited research on the direct effects of hair coloring during pregnancy or breastfeeding, it's generally recommended to avoid chemical hair treatments during these times as a precautionary measure. Certain chemicals used in hair coloring products may be absorbed into the bloodstream and potentially affect the fetus or pass into breast milk.
- Recent chemical treatments: If you've recently undergone another chemical treatment on your hair, such as a perm or relaxer, it's important to wait before coloring your hair. Coloring your hair too soon after a chemical treatment can cause excessive damage and breakage.
- Scalp injuries or infections: If you have any scalp injuries, cuts, or infections, it's important to wait until they heal completely before coloring your hair. Coloring your hair with an open wound or infection can lead to further irritation and complications.
- Certain medications: Some medications can interact with hair coloring products, causing unexpected or adverse effects. If you're taking any medications, it's important to talk to your doctor or pharmacist before coloring your hair.

- Damage and breakage: Coloring your hair soon after a chemical treatment or with an injured scalp can cause excessive damage, leading to weak, brittle hair that is prone to breakage.
