A nontrivial scalar solution proposes a weak scalar hair. A dressed black hole shows a trace of scalar charge in the metric signalling the presence of scalar hair. A number of metrics with regular horizons and temperatures are also proposed.13 pages, 4 figuresGeneral Relativity and Quantum Cosmologytext
