What can you do to add volume to thin hair that does not involve a lot of styling?

Hi Anaisa: I am going to answer your question based on two things I am understanding from your question. 1. You don't have a lot of time and 2. You want something that will not damage your hair. I have been a hairstylist for over twenty years and having fine hair myself my first concern is always to protect the hair and provide the service requested with the least amount of damage possible. I am not opposed to chemical services at all on fine hair but they must be done by someone who is very knowledgeable. While most people are more concerned with price than quality they tend to stray to the chain salons with the forty dollar special. Take into consideration before going that way that the products that will be used on your hair will be most likely very harsh and the end result will be a mess. Therefore my advice to you while taking these things into consideration would be this: Start with basic things and work from there. Here are a few tips:
A GOOD HAIRCUT IS ESSENTIAL TO EASY STYLING.
1. Use a volumizing shampoo and conditioner (These do not have heavy moisturizers in the hair that weigh them down) **Most people tend to shy away from conditioner if they have fine hair but it is truly essential.
****Some of the great products I use are: EUFORA- Volumizing shampoo and daily balance conditioner or PUREOLOGY - volumizing shampoo and conditoner
2. Always always always finish your shampooing regimen with a cool rnse. This closes the cuticle of the hair down and provides shine
3. Towel dry very good using a squeezing technique instead of rubbing ( Hair can stretch up to fifty percent in length when wet and the rubbing method tends to create splitting and breaking.
4. Apply a small amount of volumizing solution and comb through the hair. I use PUREOLOGY - volumizing blow drying glaze
5 If time allows wrap hair up in towel while applying makeup getting dressed etc. (This llows excess moisture to be squeezed out cutting blo dry time in half and eliminating frizziness
6. When you begin to blo dry flip head upside down and move hair off your scalp for the first couple of minutes.
7. If you use a round brush on your hair be sure to direct hair up toward the ceiling and allow the hair to cool on the brush before removing.
