Summer Hair Care Tips

Consider some of these basic tips for preventing unnecessary damage and having great summer hair:

1.  Give your tresses a summer shampoo break

Shampoo less often to allow tresses to absorb natural oils.  Or switch to more gentle cleansing methods which won't dry out sun exposed strands.  Opt for Conditioner Only (CO) or Diluted Shampoo (DS) washes.
Hair needs to be treated more gently during the summer. Consider switching to a more moisturizing and overall gentle shampoo formulas like Phytonectar, Phytojoba or similar.
When possible, finish with a cool to cold rinse to seal the hair cuticle and impart natural shimmer.

2.  Go natural

During summer months when hair tends to be moisture deprived, limit use of hair chemicals (bleach, hair color, relaxers, chemical straigteners) as much as possible.
Depending on your hair type, texture and condition you may wish to consider avoiding hair care products which contain known ingredients (some forms of alcohol) which may be drying to some type, textures or condition of hair.
Consider switching to hair care products which are as natural as possible. 

3.  Back off heated hair styling tools

If you normally use hot styling tools (blow dryers, hot irons, rollers), give your hair a rest during summer months. Air dry whenever possible or opt for easy chic styles. 
Braid damp tresses waves which create natural waves as the hair air dries.  Play with half up/half down styles or Boho side braids.
If you're attached to your blow dryer and can't give it up, use a leave- in conditioner designed to protect your hair against dryer heat.  When you do blow dry, dry on high heat.
Why?  It's actually much better to dry with high heat because you expose your hair to heat for a shorter period of time than you would if you used medium heat.
