This might be "2150: The Macro Love Story", also titled "2150 A.D." According to the ISFDB, it was originally published in 1971 with authors Don and Thea Plym, but was later republished as being by only Thea Alexander.
The protagonist, Jon Lake, living in the 1970s, has dreams in which he lives in a future utopian 2150 society. On his first visit, he meets the woman Lea, who introduces him to the society. Although the people are not bald, they generally have short hair. From Chapter 4:
I was impressed with the sheer physical size and beauty of my fellow Alpha members. I was also surprised at the lack of hair. Of the five males my hair was the longest, and it was short by 1976 standards. Even among the girls the longest hair was Carol's, which was no more than four inches at most.
When I asked Carol about this she informed me that they did not value hair because they were not vain about their appearances. It was simpler, she assured me, to keep their hair short.
The society is regulated by the unifying so-called Macro philosophy and people have lots of psychic superpowers, including telepathy. From Chapter 4 again:
One's level of awareness was indicated by the color of his tunic. The tunic, I learned, was a perfectly accurate reflection of one's aura, which was an unfailingly accurate indicator of one's state of being, mentally, emotionally, spiritually, and physically. ...
These degrees of awareness were based on the extent to which a person demonstrated the three Macro qualities: love, wisdom, and leadership, in that order of importance, and the seven Macro powers: clairvoyance, telepathy, precognition, retro cognition, psycho kinesis, telekinesis, and astral projection. [See C.I. Excerpts].
Jon Lake goes back and forth between the 1970s and 2150 for a while in an attempt to gain enough "macro awareness" to live in 2150 permanently, but unfortunately doesn't succeed.
