Thanks for posting your query at DoctorSpring.com
To help the wound heal, ideally you should take an oral antibiotic too with topical medicine. Also clean the area daily with betadine solution. As two days have already passed, it is not advisable to get the wound stitched.
Once the lesion heals, you may use silicone based gel twice in a day for minimal scarring. If the scar is too deep to destroy hair follicles, the hair growth will be affected and nothing can be done to restore the same. But the good thing your wound does not look too deep, however I will still like to see a few more images.
I will request you to share a few more high resolution images from slightly close by for me to one again review the wound.
Feel free to discuss further,

Thanks so much for the response. I've attached a few more photos - it was tough to get close, in focus shots of the wound.
I woke up yesterday to see what looked like the start of an infection, with pus. I went out to get Betadine and have been washing every 4-5 hours or so with it, and it looks better. I'd prefer not to go see a doctor and take oral antibiotics, but do you have a suggestion for when to tell if the wound looks bad enough to warrant it?
Thank you for the suggestion of silicone gel for healing scars. Do you have any suggestion for what brand may work best? Also, any suggestions for any other type of topical ointment for treatment?
Thank you again,
Just do a course of oral and topical antibiotic and clean the area with betadine solution. You may take amoxycillin clavulinic acid 625 mg thrice in a day as an oral antibiotic( adult dose) for faster healing. As the wound is in scalp even if hair loss is there, it wont be visible. Also ideally after an injury, anti tetanus vaccine should be given with in six hours.
Having said all this, it is advisable that you meet a doctor nearby for proper examination.
