DH Estetica Beauty Salon in South End Boston is happy to offer a full range of hair extensions services.

You are going to have extensions in from 2 to 6 months, and the service is not cheap. The right assessment is the key!!!!
Please invest some time into consulting with a stylist to pick the brand, texture, length and color that you meet your needs.

  1. You might need to color your hair first to match it to the hair extensions color. There usually around 50-60 colors in each brand’s palette which seems to be more than enough… However a slight color correction might be needed, so called color matching
  2. The stylist needs to see and feel your hair to pick the right texture and the amount of hair extension pieces. The time of service varies greatly depending on how many pieces need to be put in. Of course the time of service depends on the type of extensions you want.

The core of capsular hair extensions is that hair strands are being attached to natural hair with capsules to provide reliable fixation, durability and blended look. Such extensions don’t require frequent corrections, and there are only few minimal restrictions for hair aftercare. You can visit a sauna, a bath, a sunbed, wash and color extended strands.*

Tape in hair extensions are suitable for any hair length and density. The procedure takes less time than capsular one , it can take around an hour. Fixation of strands is made without application of high temperature.

You would need corrections every in salon 2 months. Besides, tape in hair extensions have a set of restrictions. You shouldn’t style your hair with hot blow dryer , visit sauna, or use certain hair sprays.

What hair extensions are better: capsular or tape in?

Every 3 months you should make correction since your natural hair grow longer.

The capsules provide very strong connection therefore attached hair strands hold for a long time. Gradually the zone of connection goes down and capsules become noticeable. During adjustment the hair stylist will dissolve capsules by special compounds and disconnect the extensions without damaging your hair. To remove keratin leftovers, the stylist will carefully comb your hair with fine tooth hairbrush. Then hair extensions will be attached with new capsules closer to your roots. Such correction can be done up to 3 times a year.

Correction and removal of hair extensions

Your hair needs special care after applying hair extensions. Treat your hair carefully and follow these recommendations:
  • Before washing your hair, accurately untangle or comb it with a special hair extensions brush
  • Do not use regular hairbrushes or brushes with the rounded prongs, they can damage capsules. Get a special hairbrush to take care of your hair.
  • To wash your head use shampoos that contain no silicone or oily components
  • Do not use hair masks or balms that contain oils (natural or synthetic) ON THE ROOTS, they can dissolve keratin capsules and provoke rejection of hair extensions strands.
  • Wash your head in a vertical position under a shower without inclining forward.
  • Do not go to bed when your hair is wet, otherwise hair will get tangled and it will be impossible to comb them in the morning.
  • Do not comb wet hair, wait until it is half dry in the natural way.
  • Do not touch your roots when applying cosmetic or styling balms or gels to prevent damage of the capsules.
  • During hot styling or ironing keep the blow dryer 4 inches away from your head, otherwise the capsules will melt under the influence of high temperature.

How to take care of permanent hair extensions

Italian hot application — the most preferable option of this procedure. It can be done even on short hair (5 inches long minimum required). The master selects color and texture of hair extensions to match original hair color. The strand with keratin capsule on the end will be attached to the natural strand and clamped by the hot pliers. Under the influence of high temperature the capsule melts and becomes flat and invisible. Thus, in 2-3 hours of laborious work, the expert can add the required number of hair extensions. Usually 70 strands is enough to add volume, for the length and volume hair extensions 150 to 200 strands will do the work.

This Italian technology provides reliable fixation which makes it possible to color them and style any way you want , visit a swimming pool, a sauna without being afraid of the fact strands will fall out. At the same time you shouldn’t use cosmetics hair care products that contain silicone, acids or oils as they can destroy the capsules causing hair extensions to fall.

Micro capsules or micro ring application is ideal coarser thicker hair as the capsules are as adjustable in size as they are in keratin bonds.

Hot and Cold Procedures for Capsular hair extensions

The application process of hair extension should be done in a hair salon and results in providing additional longer curls and strands and/or more volume to your natural hair. The capsular technology of hair extension can be hot or cold, you and your hair extensions specialist will determine what option will be best suitable for your hair.

What kind of procedure is it? The hair stylist will attach and fix extensions with keratin capsules which are being melted by special hot pliers heated to a necessary temperature. When cooled, the capsules become absolutely transparent on your hair that’s why this method is applicable for any hair color. Capsules can be of any form (flat, round), everything depends on type of hair extensions.

Capsules are being attached at a distance of 0.2-0.4 inches from your scalp. The procedure may last from 2 to 4 hours, during this time the master can attach 100 – 200 strands. This provides long durability, easy to use technology and safety during the application or removal. Keratin capsules are absolutely transparent and blend in perfectly with your natural hair. They provide strong and reliable attachment and do not require special expensive hair care. Hair extensions look live, soft and silky, you can easily comb your hair and wash with shampoo the same way as your natural hair, you can cut or color hair extensions as well (varies in different brands).

The number of added hair extensions in many ways depends on desirable end result and effect. Everything depends on the initial length and density of your natural hair. The unique technology allows you to experiment, so that you can use hair extensions of different shades and gain a stunning effect of highlights or in one evening you can change your look totally from short haircut to long, brilliant curls down to waist. Hair extension would need correction every 2-4 months – while your own hair grows the capsules with extensions go down. During the adjustment procedure the stylist will transfer the capsules closer to your roots again.
