HSI Professional vs Onei MK-I Halo

The infrared technology deeply penetrates the hair and heats it from inside out. The hair is heated evenly and much quicker than by a hair straightener without this technology. This means styling in half the time, thus reducing the heat damage.

The curved shape of the plates helps to create curly and wavy hair styles.

The tourmaline which is infused in the ceramic plates, produces negative ions which heat the hair quickly and thoroughly, thus lessening the damage and adding shine to the hair.

The HSI has a shut-off time setting which can be adjusted between 10 and 60 minutes. This is for added security in instances when the hair straightener has been left unattended when still hot.

The straightener comes with an insulated satin bag, which allows storing the straightener in a safe place when it is still warm. It also doubles up as a travel bag for when you wish to take it with you.

This hair straightener has an LCD temperature control which allows you to change the heat setting between 115° C (239° F) and 230° C (446° F). It has a heat setting for every hair type - lower ones for thin, short, and brittle hair, and higher temperature for curly, thick, and long hair.

The adjustable heat setting allows the user to select the right temperature for their hair type, therefore making the straightening and styling process simple and easy. As it heats up to 230° C (446° F), it is well suited for those with thick and curly hair.

The heat glove that comes together with the straightener, helps to prevent accidental burns during the straightening process. This is especially handy when handling just straightened hair which might still be hot from the plates.

It heats up in less than 10 seconds, which is ideal for those who are in a rush or have limited time to spend styling their hair.

The built-in infrared technology heats the hair hair molecules from within, thus straightening it evenly and in a short period of time. In addition to that, the ionic technology adds shine and helps prevent frizziness.

Onei MK-I Halo has a heat range between 60º C (140º F) and 230ºC (446º F), which is suitable for any hair type and even Brazilian keratin treatments. Use lower temperature setting for fine, short, and brittle hair, and higher temperature setting for long, thick, and curly hair.

It cools down quickly after usage , therefore limiting the heat related accidents such as burns on the hands and heat damage on the surrounding surfaces.

For added safety - this straightener offers 30 minute shut-off time, if it hasn't been used for a while. This reduces the risk of accidents when left unattended.

Should any issues arise, it comes with a 4 year warranty for peace of mind.
