I use pine nut oil to treat my split ends. Because my hair tends to be greasy, I can’t yet bring myself to use it in its pure form, but use it as a supplement to a mask and balsam for my hair. For my hair, which is fairly dry at the ends, I personally add five to six drops to a mask and a balsam, the main thing is not to overdo it, otherwise, my hair becomes greasy and clumps together. The oil has moistened my hair and has repaired my split ends.
