Our advice to evaluate a rehairing.

- if the hairs are pulled out from the head or the frog, it could be a loosening of a weak node in the “mortes”.
- if the hairs break too easily or stretch too much, or they are of poor quality or the flame on them is used to “stretch them” (bad procedure, here is bandit!). There may be other causes, but they are more rare.
- if the bow leap too easily, compared to before, maybe a wrong number of hairs have been mounted.
- if they wooden tap slip out from the “mortes” of the frog or head, it means the mortes may not have been properly adjusted.
- if you find a split tip and before it was not, probably the wooden tap has been plugged too much pressurized.
- if the frog breaks off, a wooden tap in the wood will probably be too pressurized.
