Brief Answer: its a part of ageing process. Detailed Answer: Hi, Thanks for writing to us. Graying of hair or canities is an ongoing ageing process. Usually after thirty years of age, our hair gradually start to lose pigment cells. Now this process could be accelerated in few due to herediatary factors, stress, smoking, nutrition etc. As your head has completely turned white with few gray white hair in forearm and eye brows, it just means that this ongoing process is slightly accelerated in your case. This could have also occured if your hair had started turning gray earlier ie in your twenties. To treat the same, nothing can be done. Please stop worrying about these. It's just a part and parcel of turning wiser with age! Hope this answered your query. Take care
