How to Make Your Hair Grow Faster #long_hair

There are three steps of hair growth, says Phillips. "They include: Anagen, the actual growth phase; Catagen, the rest phase, which lasts three or four months; and Telogen, when your hair unanchors from the follicle and sheds away naturally." Obviously not every hair is on the same cycle, which is why we have hair on our heads at all times. But it's important to know where your hair might be in it's growth phase, so you don't get frustrated when trying to grow your hair longer like Selena's.

Minimize Any Hair Damage

It's always good to treat your hair with a little extra TLC, like Kim clearly does. That means minimizing the amount of times you color your hair in a year, turning down the heat on your hot tools, and keeping your blow dryer moving when you use it (because if you hold it in one place too long, it could burn your hair).

It's also good to use a heat protectant spray, says Phillips, which covers each strand with a protective layer so your hair don't burn, become brittle, and break off. Try L'Oreal Advanced Haircare Color Vibrancy Dual Protect Spray, $7.

What Stunts Hair Growth

"Genetically we're programmed to our rate of growth," says Phillips. However, she told Cosmo that you can improve your lifestyle and hair choices that you make to increase the length of your hair to be long llke Kelly's.

Here are the most known culprits of stunted hair growth that happen internally and externally:

Your general internal health contributes to how long your hair is. So, issues like thyroid problems, hormonal imbalances, etc. could stunt hair growth. Nutrition (weight fluctuation, crash or restrictive diets, high exercise and not enough protein, iron deficiency, etc.) also plays a role in how long your hair will grow. And lastly, stress.

Externally, we are constantly traumatizing our hair by pulling it back too tightly, using hot tools on a too-high temperature, brushing it too hard, and basically doing a number on it and beating it to the growth phase punch.

Take Vitamins and Supplements

An all-purpose multivitamin promotes balance, so if you have low B12, zinc or iron, this will help raise your levels and allow your hair to get the nutrients it needs to grow longer and faster, like Naya's.

"Any OTC multivitamin will do the trick, but the protein supplement I recommend is the Phillip Kingsley PK4 Soya Protein Capsules, $35. They're made out of a soy-based complex with Amino acids, the building blocks of keratin, which is the protein that hair is made up of, so your hair grows faster and stronger."

Biosil, $16 and Viviscal, $43 are two additional supplements that also grow hair longer faster. Hairstylists also swear by then when recommending ways to help their celebrity clients' hair grow out after getting a short cut for a movie, etc.

Condition Your Hair Often

"Just like you moisturize your facial skin after you wash it, it's important to do the same for your scalp skin," says Phillips. Conditioning on the regular and using leave-in conditioners are the perfect ways to maintain optimal scalp health, which is crucial to growing Beyoncé-long hair.

Give Your Scalp a Facial

"The follicles on your head sit a milimeter and a quarter beneath the scalp and are the bedrock of healthy hair," says Phillps. So, much like your facial skin, it's important to take care of it properly and keep it at its optimal health, like Gisele's.

To do so, she suggests doing a hair mask once a week to treat both the scalp and your strands. Try Phillip Kingsley Stimulating Scalp Mask, $9, or Clear Scalp & Hair Beauty Therapy Damage & Color Repair Deep Nourishing Treatment Mask, $14.
