Will A Guinea Pig’s Hair Grow Back: How Long Can That Take?

Guinea pigs can lose their hair for different reasons like if they got a bad haircut, if they’re scratching or biting too hard because they have mites, or if they have been injured and their skin starts to scar up.

Once you notice the hair loss it can seem like nothing is happening at the time, so will a guinea pig’s hair grow back?

A guinea pig’s hair will grow back and it usually takes about a month for it to start to look like it’s filling in properly.

That being said, the time it takes for a guinea pig’s hair to grow back depends on what caused them to lose their hair in the first place.

Each situation is different so sometimes you won’t have to do anything for it to grow back regularly and other times they may require some type of hair loss treatment.

Will A Guinea Pig’s Hair Grow Back?

When it comes to guinea pigs generally their hair grows back constantly throughout their lives and it still does even as they get older.

So for example, if your guinea pig recently got a haircut and they don’t look how you want them to look, then everything will be okay because their hair will grow back.

Guinea pigs can go through hair loss if they have mites that they’ve been scratching or biting at for a while.

So if it’s hair loss from something like that then you should get some good advice from a veterinarian on what kind of treatment you should do.

If the treatment is successful then after some time the hair should start growing back.

However, it will only start to grow back after all of the mites have been fully removed from the guinea pig.

Sometimes a guinea pig can lose some of its hair after an injury has taken place when it leaves a bald patch where the skin is scarred.

So if this happens and the scarring is too deep and the skin is too damaged then the hair may have a hard time growing back.

In some cases, the hair may not grow back at all if the skin is too damaged, so that’s definitely something to be prepared for.

If the scarring is not that deep then the hair should grow back, but it may grow a little slower than it regularly would.

So in most situations, a guinea pig’s hair will grow back as long as you give it some time to grow.
