Hair Type Considerations When Using Glycolic Acid For Hair
Glycolic acid can be used for almost all hair types, but if you have very sensitive hair and scalp you might need to check in with your doctor or start by using very low concentrations of glycolic acid before using higher concentrations.
If you have an oily scalp, then you would definitely love glycolic acid on your scalp. One of the instances one should take caution while using glycolic acid for hair is if your hair and scalp have any health conditions like extreme sensitivity, hair loss, or other severe scalp skin issues. People with high sensitivity might find glycolic acid to be too harsh for them as it can lead to extreme dryness, itchiness, and rashes.
Also, use the product in moderation especially while starting out, We recommend sticking to it once or twice a week. Depending on the cut you are using and its strength you might even want to start off with just once a week as a hair mask, instead of leaving the product on your scalp for longer hours. Also, avoid using glycolic acid for hair if you have done any hair treatment like perming, smoothening, straightening, or rebonding, or if your hair is already very damaged.
The Right Way To Use Acid For Hair
Using glycolic acid for hair the right way is very important to get optimal benefits as well as to reduce the side effects. Exfoliating the scalp is very similar to exfoliating the face or body. While starting to use any exfoliating products always remember that “less is always more”. Over-exfoliation can not only make your scalp health worse but can also cause inflammation, and dryness and even lead to hair fall. Experts recommend using glycolic acid at night rather than in day time to reduce sun damage.
Sun can sensitize the scalp. If you find using a potent glycolic acid, like the Ordinary 7% glycolic acid toning solution, dicey as a beginner, it’s better to start your glycolic acid for hair care journey by using products with glycolic acid that is formulated for hair care. These products will have lower percentages of glycolic acid in them as well as other ingredients to overcome dryness and sensitivity, so as a beginner these kinds of products would be your best choice.
Once your scalp gets used to glycolic acid then you can try using a higher percentage. Never use a glycolic acid that is more than 7 % on your hair without a doctor’s recommendation, that could be too much and cause damage to your scalp.
Note: if you have a very sensitive scalp that reacts to new products then do get an expert opinion before trying out anything new. Doctors can analyze and understand your scalp and recommend the best products that will suit your scalp. If you wish to try glycolic acid then do talk to your doctor to find the right percentage of glycolic acid for your hair.
