I very much doubt you`ll get 6 months from a system..it`s possible, but not the norm [you`d be doing well to get around 3 months].... the hair will usually have begun to shed out /break off long before that..... I got some lifting of the lace from my tape last week for the first time in a long time... I put it down to [ possibly] some of the silicones in the spray ..... I gave the system a shampoo / conditioning and haven`t had that ` lifting` since ... I am using the `Enhance` full-time now again ..... a little of it goes a long way ..just 2 or 3 darts of it into damp hair, style it lightly and allow the dry naturally ...gives a light ` hold` which brushes out easily...... been using it for a long time and can really recommend it ..... the silicone -containing one is good ...I possibly applied it a bit too heavily.... will use it again, but more lightly.
