Hair and scalp essence recommendations

Lately, I've been thinking a lot about the importance of taking care of my scalp as well as using hair essence on my hair. The sweltering summer sun seems to irritate my scalp, causing hair loss and itching, so I looked into tonics. I found a product called "Spring Comes" to be affordable and gentle without irritation, so I am currently using several bottles of it. I think my hair will improve if I use it consistently.
