Good hairdresser doesn't necessarily need to be expensive. I went to Vybe's Hairdresser at Bedok Central, good haircut but the waiting time can be ridiculously long. Do call before you drop by.
Well I feel that for scar treatment, creams available on pharmacy is pretty expensive. I would recommend you to try some home remedies such as Almond Oil. Really good for scar, after some time your scar will fades. It works on me tho.
