• Know your hair type (fine, thick, curly, straight, wavy)

• Focus the shampoo on the roots rather than the ends.
• Use a shampoo suited to your hair and scalp type.
• Avoid washing your hair too frequently.
• Do not wash your hair with water that is too hot.
• Massage the scalp using straight movements rather than circular motions to help prevent tangling.

• Apply a mask after shampooing.
• A mask does not replace conditioner. Apply conditioner afterward.
• Leave the mask on for 1 to 30 minutes depending on your hair's needs.
• Do not apply it to the roots; apply only to the lengths.

Apply conditioner at the very end, focusing on the lengths.

Do not apply it to the roots.

Leave on for 1 to 5 minutes.

Rinse the hair with lukewarm or cool water.

• Do not rub the hair with a towel. Gently squeeze out excess water.
• Do not wrap the hair too tightly in a towel, as this can pull out shorter hairs around the face.

• Use clean, well-maintained styling tools that are appropriate for your hair type.
• Use high-quality styling tools.
• Do not use a flat iron above 380°F.
• Detangle the hair before using a flat iron.

• Use the right type of hairbrush.
• Take smaller sections when using a flat iron for better results.
