Used correctly, hair oil is your extensions’ best friend<\/strong>: it moisturizes the ends, adds shine and prevents tangling. Used incorrectly, it is their worst enemy \u2013 oil softens tape adhesive and keratin bonds, causing extensions to slip. This guide explains which oils suit extensions and how to apply them properly.<\/p>\n

The most important rule: oil on lengths only, never on attachments<\/h2>\n

Never apply oil on tapes, keratin bonds or any attachment points, and avoid the scalp area near them. The safe zone starts about 5\u201310 cm below the attachments: mid-lengths and ends. This rule applies to all oil-based products, including oil-containing leave-in sprays.<\/p>\n

Which oil suits extensions?<\/h2>\n\n\n\n\n\n\n\n\n
Oil type<\/th>\nSuitability for extensions<\/th>\nUse<\/th>\n<\/tr>\n<\/thead>\n
Argan oil<\/strong><\/td>\nExcellent \u2013 lightweight, absorbs quickly<\/td>\nOn damp ends after washing<\/td>\n<\/tr>\n
Jojoba oil<\/strong><\/td>\nExcellent \u2013 similar to hair’s natural sebum<\/td>\nSmall amount on dry ends daily<\/td>\n<\/tr>\n
Light oil serums<\/strong><\/td>\nGood \u2013 easy to dose<\/td>\nFinishing shine and anti-static<\/td>\n<\/tr>\n
Heavy oils (e.g. coconut)<\/strong><\/td>\nWith caution \u2013 can weigh hair down<\/td>\nOnly as an intensive end treatment, washed out<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Choose an alcohol-free product, as alcohol dries out human hair. Remember that extension hair receives no natural oils from your scalp, so the ends need oil more often than your own hair does.<\/p>\n

Building an oil care routine<\/h2>\n
    \n
  1. After washing:<\/strong> apply 1\u20132 drops of oil to damp mid-lengths and ends.<\/li>\n
  2. Before heat styling:<\/strong> a small amount of heat-protective serum on the lengths.<\/li>\n
  3. Daily as needed:<\/strong> a drop of oil on dry ends and against static.<\/li>\n
  4. Once a week:<\/strong> a deep moisturizing mask on the lengths \u2013 not on the attachments.<\/li>\n<\/ol>\n

    Always brush your hair before oiling with the correct brushing technique<\/a> so the product spreads evenly.<\/p>\n
