False.
The visible hair shaft is made of dead, keratinized cells and contains no living tissue. However, the hair follicle and hair matrix (the part beneath the scalp that produces the shaft) are living and do need blood-delivered nutrients and vitamins for healthy growth. Poor nutrition (eg, protein, iron, zinc, biotin/vitamin B7, vitamin D deficiencies) can cause thinning or slowed growth.
