The picture might look delicious but it's not edible! This hair mask works as a deep conditioner and it's one of my favorite at-home SPA hair treatment. Since Valentine's day is coming up, give your hair a little treat and a break from all those styling. What this mask does: It leaves your hair feeling weightless and looking shiny and smooth. This is due to the anti-fungal and moisturizing property of strawberries. Method: Blend 8 strawberries and 2 tablespoons of mayonnaise to form a cream. Apply generously to wet hair. Leave mask on for 15 minutes and shampoo as normal.
